The sections of piping immediately upstream and downstream of a primary flow measuring device are known as

Answers

The sections of piping immediately upstream and downstream of a primary flow measuring device are known as the "straight run."

The straight run refers to the lengths of piping that are required to be present immediately upstream and downstream of a primary flow measuring device. These sections of piping are necessary to ensure that the flow profile is fully developed and unaffected by any disturbances caused by bends, fittings, or obstructions in the pipe. The straight run allows the fluid to flow smoothly and uniformly before entering or exiting the flow measuring device, ensuring accurate and reliable measurements.

By providing sufficient straight run lengths, the flow profile becomes stable, minimizing turbulence and disturbances that could impact the accuracy of the flow measurement.

Take the contact angle at the inner wall of the tube to be 6 0 and the surface tension to be 1.00 N/m

Answers

The maximum capillary rise and tube diameter for this maximum-rise case will be d=0.414× 10⁻⁴ m.

What do you mean by tube?

A tube, also known as tubing, is a long hollow cylinder that is used to transport fluids (liquids or gases) or to protect electrical and optical cables and wires.

Given that, P = 4 KPa

Contact angle = 6°

Surface tension = 1 N/m

Lets assume that atmospheric pressure = 100 KPa

Lets take that density of water = 1000kg/m³

So the capillarity rise h

h=ΔP/ρg

h= (100×1000-4×1000)/(1000×10)

h= 9.61 m

We know that for capillarity rise h

h=2σcosθ/rρg

r = 2σcosθ/hρg

Answers

Answer:

A) Not possible, B) Posible, C) Possible, D) Not possible.

Explanation:

The maximum theoretical efficiency for any thermal engine is defined by Carnot's cycle, whose energy efficiency (\(\eta\)), no unit, is expressed below:

\(\eta = 1-\frac{T_{L}}{T_{H}}\) (1)

Where:

\(T_{L}\) - Cold reservoir temperature, in Kelvin.

\(T_{H}\) - Hot reservoir temperature, in Kelvin.

If we know that \(T_{L} = 250\,K\) and \(T_{H} = 750\,K\), then the maximum theoretical efficiency for the thermal engine is:

\(\eta = 1-\frac{T_{L}}{T_{H}}\)

\(\eta = 0.667\)

For real thermal engines, the following inequation is observed:

\(0 \le \eta_{r} \le \eta\) (2)

Where \(\eta_{r}\) is the efficiency of the real heat engine, no unit.

There are two possible criteria to determine if a given heat engine is real:

Efficiency

\(\eta_{r} = 1 - \frac{Q_{L}}{Q_{H}}\) (3)

Where:

\(Q_{L}\) - Heat rejected to the cold reservoir, in kilojoules.

\(Q_{H}\) - Heat received from the hot reservoir, in kilojoules.

Power output

\(W = Q_{H}-Q_{L}\) (4)

Where \(W\) is the power output, in kilojoules.

Now we proceed to verify each case:

A) \(Q_{H} = 900\,kJ\), \(Q_{L} = 600\,kJ\), \(W_{m} = 400\,kJ\)

\(\eta_{r} = 0.333\)

\(0 \le \eta_{r} \le \eta\)

\(W = 300\,kJ\)

\(W \ne W_{m}\)

This engine is not possible.

B) \(Q_{H} = 900\,kJ\), \(Q_{L} = 500\,kJ\), \(W_{m} = 400\,kJ\)

\(\eta_{r} = 0.444\)

\(0 \le \eta_{r} \le \eta\)

\(W = 400\,kJ\)

\(W = W_{m}\)

The engine is possible.

C) \(Q_{H} = 900\,kJ\), \(Q_{L} = 300\,kJ\), \(W_{m} = 600\,kJ\)

\(\eta_{r} = 0.667\)

\(0 \le \eta_{r} \le \eta\)

\(W = 600\,kJ\)

\(W = W_{m}\)

The engine is possible.

D) \(Q_{H} = 900\,kJ\), \(Q_{L} = 100\,kJ\), \(W_{m} = 800\,kJ\)

\(\eta_{r} = 0.889\)

\(\eta_{r} > \eta\)

\(W = 800\,kJ\)

\(W = W_{m}\)

The engine is possible.

Hence the magnitude of the pure moment m will be \(2\times 10^5.\)

Explanation:

 Width of steel fleet = 120 mm   The thickness of steel fleet = 10 mm   Let the circle of radius = 10 m  

Now,

We know that,

\(\frac{M}{I} = \frac{E}{R}\)

An electronic engine control (eec) is a system that receives engine operating information and?

Answers

An electronic engine control (EEC) is a system that receives engine operating information and processes it. It's designed to improve engine efficiency while reducing emissions.

The EEC works by collecting data from various sensors, including the oxygen sensor, coolant temperature sensor, throttle position sensor, and manifold absolute pressure sensor, among others.

Based on the data received from these sensors, the EEC can make adjustments to the engine's fuel and air mixture, ignition timing, and other parameters to optimize engine performance.The EEC's primary function is to regulate fuel delivery to the engine.

The system uses data from the oxygen sensor to determine the air/fuel ratio, which it then adjusts by altering the fuel injector pulse width. This process helps ensure that the engine is always running at its most efficient, reducing fuel consumption and emissions.

The EEC also monitors the engine's other systems, such as the ignition system and transmission. If a problem is detected, the EEC will activate a warning light on the dashboard, indicating that the driver should take the vehicle to a qualified mechanic for inspection.

The EEC is an essential part of modern engine management systems, allowing for precise control of the engine's performance. It has made significant contributions to the improvement of engine efficiency and environmental impact.

A lake with a surface area of 525 acres was monitored over a period of time. During onemonth period the inflow was 30 cfs (ie. ft3 /sec), the outflow was 27 cfs, and a 1.5 in seepage loss was measured. During the same month, the total precipitation was 4.25 inches. Evaporation loss was estimated as 6 inches. Estimate the storage change for this lake during the month.

Answers

Answer:

The storage of the lake has increased in \(4.58\times 10^{6}\) cubic feet during the month.

Explanation:

We must estimate the monthly storage change of the lake by considering inflows, outflows, seepage and evaporation losses and precipitation. That is:

\(\Delta V_{storage} = V_{inflow} -V_{outflow}-V_{seepage}-V_{evaporation}+V_{precipitation}\)

Where \(\Delta V_{storage}\) is the monthly storage change of the lake, measured in cubic feet.

Monthly inflow

\(V_{inflow} = \left(30\,\frac{ft^{3}}{s} \right)\cdot \left(3600\,\frac{s}{h} \right)\cdot \left(24\,\frac{h}{day} \right)\cdot (30\,days)\)

\(V_{inflow} = 77.76\times 10^{6}\,ft^{3}\)

Monthly outflow

\(V_{outflow} = \left(27\,\frac{ft^{3}}{s} \right)\cdot \left(3600\,\frac{s}{h} \right)\cdot \left(24\,\frac{h}{day} \right)\cdot (30\,days)\)

\(V_{outflow} = 66.98\times 10^{6}\,ft^{3}\)

Seepage losses

\(V_{seepage} = s_{seepage}\cdot A_{lake}\)

Where:

\(s_{seepage}\) - Seepage length loss, measured in feet.

\(A_{lake}\) - Surface area of the lake, measured in square feet.

If we know that \(s_{seepage} = 1.5\,in\) and \(A_{lake} = 525\,acres\), then:

\(V_{seepage} = (1.5\,in)\cdot \left(\frac{1}{12}\,\frac{ft}{in} \right)\cdot (525\,acres)\cdot \left(43560\,\frac{ft^{2}}{acre} \right)\)

\(V_{seepage} = 2.86\times 10^{6}\,ft^{3}\)

Evaporation losses

\(V_{evaporation} = s_{evaporation}\cdot A_{lake}\)

Where:

\(s_{evaporation}\) - Evaporation length loss, measured in feet.

\(A_{lake}\) - Surface area of the lake, measured in square feet.

If we know that \(s_{evaporation} = 6\,in\) and \(A_{lake} = 525\,acres\), then:

\(V_{evaporation} = (6\,in)\cdot \left(\frac{1}{12}\,\frac{ft}{in} \right)\cdot (525\,acres)\cdot \left(43560\,\frac{ft^{2}}{acre} \right)\)

\(V_{evaporation} = 11.44\times 10^{6}\,ft^{3}\)

Precipitation

\(V_{precipitation} = s_{precipitation}\cdot A_{lake}\)

Where:

\(s_{precipitation}\) - Precipitation length gain, measured in feet.

\(A_{lake}\) - Surface area of the lake, measured in square feet.

If we know that \(s_{precipitation} = 4.25\,in\) and \(A_{lake} = 525\,acres\), then:

\(V_{precipitation} = (4.25\,in)\cdot \left(\frac{1}{12}\,\frac{ft}{in} \right)\cdot (525\,acres)\cdot \left(43560\,\frac{ft^{2}}{acre} \right)\)

\(V_{precipitation} = 8.10\times 10^{6}\,ft^{3}\)

Finally, we estimate the storage change of the lake during the month:

\(\Delta V_{storage} = 77.76\times 10^{6}\,ft^{3}-66.98\times 10^{6}\,ft^{3}-2.86\times 10^{6}\,ft^{3}-11.44\times 10^{6}\,ft^{3}+8.10\times 10^{6}\,ft^{3}\)

\(\Delta V_{storage} = 4.58\times 10^{6}\,ft^{3}\)

The storage of the lake has increased in \(4.58\times 10^{6}\) cubic feet during the month.

The volume of water gained and the loss of water through flow,

seepage, precipitation and evaporation gives the storage change.

Response:

The storage change for the lake in a month is 1,582,823.123 ft.³

How can the given information be used to calculate the storage change?

Given parameters:

Area of the lake = 525 acres

Inflow = 30 ft.³/s

Outflow = 27 ft.³/s

Seepage loss = 1.5 in. = 0.125 ft.

Total precipitation = 4.25 inches

Evaporator loss = 6 inches

Number of seconds in a month is found as follows;

\(30 \ days/month \times \dfrac{24 \ hours }{day} \times \dfrac{60 \, minutes}{Hour} \times \dfrac{60 \, seconds}{Minute} = 2592000 \, seconds\)

Number of seconds in a month = 2592000 s.

Volume change due to flow, \(V_{fl}\) = (30 ft.³/s - 27 ft.³/s) × 2592000 s = 7776000 ft.³

1 acre = 43560 ft.²

Therefore;

525 acres = 525 × 43560 ft.² =  2.2869 × 10⁷ ft.²

Volume of water in seepage loss, \(V_s\) = 0.125 ft. × 2.2869 × 10⁷ ft.² = 2,858,625 ft.³

Volume gained due to precipitation, \(V_p\) = 0.354167 ft. × 2.2869 × 10⁷ ft.² = 8,099,445.123 ft.³

Volume evaporation loss, \(V_e\) = 0.5 ft. × 2.2869 × 10⁷ ft.² = 11,434,500 ft.³

\(Storage \, change \, \Delta V = \mathbf{V_{fl} - V_s + V_p - V_e}\)

Coal containing 21% ash is completely combusted, and the ash is 100% removed in a water contact scrubber. If 10,000 kg of coal is burned per hour with a scrubber flow rate of 1.0 m3/min, the weight percentage of the ash in the water/ash stream leaving the scrubber is most nearly:_______.
a. 3.4
b. 14.3
c. 25.9
d. 67.7

Answers

Answer:

Weight Percentage of Ash = 3.4

Explanation:

Given - Coal containing 21% ash is completely combusted, and the ash is 100% removed in a water contact scrubber. If 10,000 kg of coal is burned per hour with a scrubber flow rate of 1.0 m3/min.

To find - the weight percentage of the ash in the water/ash stream leaving the scrubber is most nearly ?

Solution -

Given that,

Coal Burned Rate = 10,000 kg/hr

                              = \(\frac{10,000}{60 min} * 1 hr *\frac{kg}{hr}\)

                              = 166.6666 kg/min

⇒Coal Burned Rate = 166.6666 kg/min

Now,

Given that,

Ash content in coal = 21 %

⇒Ash in (coal that burned) = 166.6666 × \(\frac{21}{100}\) kg/min

                                             = 34.9999 ≈ 35 kg/min

⇒Ash in (coal that burned) = 35 kg/min

Now,

We know,

Density of water = 1000 kg/m³

Now,

Water flow Rate = \(1\frac{m^{3} }{min} * density\)

                           = 1000 kg/min

⇒Water flow Rate = 1000 kg/min

Now,

Total Mass flow Rate of (Water + Ash stream) = ( 1000 + 35) kg/min

                                                                           = 1035 kg/min

⇒Total Mass flow Rate of (Water + Ash stream) = 1035 kg/min

So,

Weight Percentage of Ash = (Weight of Ash ÷ Total weight of Stream) × 100

                                            = (35 ÷ 1035) × 100

                                            = 3.38 ≈ 3.4

∴ we get

Weight Percentage of Ash = 3.4
