Answer:

Hydrostatic force = 41168 N

Explanation:

Complete question

A triangular plate with a base 5 ft and altitude 3 ft is submerged vertically in water  so that the top is 4 ft below the surface. If the base is in the surface of water, find the force against onr side of the plate. Express the hydrostatic force against one side of the plate as an integral and evaluate it. (Recall that the weight density of water is 62.5 lb/ft3.)

Let "x" be the side length submerged in water.

Then

w(x)/base = (4+3-x)/altitude

w(x)/5 = (4+3-x)/3

w(x) = 5* (7-x)/3

Hydrostatic force = 62.5 integration of  x * 4 * (10-x)/3 with limits from 4 to 7

HF = integration of 40x - 4x^2/3

HF = 20x^2 - 4x^3/9 with limit 4 to 7

HF = (20*7^2 - 4*7^(3/9))- (20*4^2 - 4*4^(3/9))

HF = 658.69 N *62.5 = 41168 N

water condition for a boiler is crucial to its performance and longevity. Proper water treatment and maintenance are essential to ensure that the boiler operates efficiently and safely. Regular monitoring of water quality, pH levels, TDS, oxygen content, and temperature is necessary to maintain optimal conditions for the boiler.

The water condition for a boiler is an essential factor to consider as it affects the efficiency, safety, and lifespan of the boiler. The following are some key factors to keep in mind when considering the water condition for a boiler:
1. Water Quality: The quality of the water used in a boiler is critical to its performance. Poor quality water can lead to scale buildup, corrosion, and even boiler failure. Therefore, the water used in a boiler must meet certain standards. This can be achieved by using treated water, such as deionized or demineralized water, or by using a water treatment system that removes impurities.
2. pH Levels: The pH level of the water in a boiler is crucial as it affects the corrosion rate of the metal. Ideally, the pH should be between 8.5 and 9.5 for steel boilers and between 7 and 9 for copper-based boilers. A pH level that is too low can cause corrosion, while a pH level that is too high can cause scale buildup.
3. Total Dissolved Solids (TDS): TDS refers to the amount of dissolved minerals in the water. High TDS levels can cause scale buildup and reduce the efficiency of the boiler. Therefore, it is essential to monitor TDS levels regularly and remove excess minerals using a blowdown system.
4. Oxygen Content: Oxygen in the water can cause corrosion and damage to the boiler. Therefore, it is essential to remove excess oxygen using a deaerator or other oxygen removal system.
5. Temperature: The temperature of the water in a boiler should be maintained at the appropriate level to prevent overheating and damage to the boiler. The temperature should be monitored regularly and adjusted as necessary.

The correct answer is Option A. The type of road surface that provides the best friction is "Asphalt."

What is friction?Friction is the resistance between two objects that opposes their movement relative to each other. For instance, if you're driving your car on the highway, the friction between the car's tires and the road surface keeps the car moving forward without slipping out of control. The friction is necessary to keep your car on the road, particularly when you're driving on a wet or slippery surface.I

n summary, Asphalt provides the best friction. Asphalt surfaces offer high skid resistance, even in wet conditions, thanks to their fine-grained, skid-resistant aggregate and an even surface. Furthermore, they provide excellent visibility, particularly at night, due to their high reflectivity. They also have a sound-deadening effect, reducing traffic noise, which can have an impact on the quality of life in the surrounding area.

The statement "The total power delivered to a pure inductor is dissipated in the form of heat" is false because the opposition to the flow of current in the coil is known as inductive reactance, which is measured in ohms.

When an electrical current flows through an inductor, it generates a magnetic field that produces a back EMF that opposes the current's direction. The power is not dissipated as heat but rather stored in a magnetic field when an ideal inductor is connected to a circuit. The inductor acts as a storehouse for magnetic energy in this scenario. When the circuit's magnetic field is developed, the inductor begins to release energy, which is then transformed into electrical energy, in an effort to preserve the magnetic field.

Power factor is the ratio of true power to apparent power in a circuit. True power is the power that is consumed by a load, while apparent power is the power that is drawn from the source. The power that is lost during the transmission of electrical energy from the source to the load is referred to as reactive power. Power factor can be calculated using the following formula:PF = True power (W) / Apparent power (VA)Hence, the total power delivered to a pure inductor is not dissipated in the form of heat, but instead, it is stored in the magnetic field.

False.The total power delivered to a pure inductor is not dissipated in the form of heat. Instead, it is stored in the magnetic field surrounding the inductor.

This is because inductors store energy in the magnetic field that surrounds them when a current flows through them. Therefore, a pure inductor has zero resistance, which means that the power consumed by it is not dissipated in the form of heat but is instead stored as a magnetic field.As a result, in an AC circuit, the total power delivered to a pure inductor will fluctuate between positive and negative values because the stored energy is continually being alternated between the magnetic field and the electrical circuit. This can be represented by the formula: P = VIcosθ, where V is the voltage across the inductor, I is the current flowing through the inductor, and θ is the phase angle between the voltage and the current.So, the statement "The total power delivered to a pure inductor is dissipated in the form of heat" is false.

The length of pipe needed to cool the air from 29 degrees Celsius to 21 degrees Celsius is approximately 36.7 meters.

The thermal resistance of the pipe is given by the equation:

R_p = (ln(D_outer/D_inner)) / (2πkL)

We can rearrange this equation to solve for L:

L = (ln(D_outer/D_inner)) / (2πkR_p)

The overall thermal resistance is equal to the sum of thermal resistances in series:

R_total = R_p + 1/(hπD_outer)

Substituting the given values into the equation, we get:

R_total = (ln(0.17/0.15)) / (2π(0.15)(36.7)) + 1/(1500π(0.17))

We can then solve for the required pipe length, L:

L = (ln(0.17/0.15)) / (2π(0.15)(R_total))

True, in an ink-jet printer, the printhead mechanism contains ink-filled cartridges.

The printhead is the component of the printer that sprays tiny droplets of ink onto the paper to create the printed image. In an ink-jet printer, the printhead moves back and forth across the paper, depositing ink droplets in precise patterns to form text and images.

Most ink-jet printers use two types of ink cartridges: one for black ink and one for color ink. Some printers may use separate cartridges for each color in order to provide more precise color control.

The ink in the cartridges is typically a liquid that contains water, colorants, and other chemicals that help to improve print quality and prevent clogs in the printhead. When the printer is in use, the ink is heated and forced through tiny nozzles in the printhead, where it is sprayed onto the paper in precise patterns.

1) 4.41 * 10^-4 kw

2) 2.20 * 10^-4 kw

Explanation:

Given data:

Filter = 500 m^3/min

dust velocity = 3g/m^3

bag ; length = 3 m , diameter = 0.13 m

change in pressure = 1 kPa

efficiency = 60%

1) Calculate the Fan power

First :

Calculate the total dust loading = 3 * 500 = 1500 g

To determine the Fan power we will apply the relation

\(n_{o} = \frac{\frac{p}{eg*Q*h} }{1000}\)    = \(\frac{\frac{p}{(3*10^{-3})* 981*( 500/60) *3 } }{1000}\)

fan power ( \(n_{0}\) ) = 4.41 * 10^-4 kw

2) calculate power drawn

change in P = 6 atm = 6 * 10^5 pa

efficiency compressor = 50%

hence power drawn = 4.41 * 10^-4 kw  * 50% = 2.20 * 10^-4 kw
