Steam enters the nozzle of an impulse turbine stage at 60 bar and 500 °C and leaves at 20 bar. Flow is adiabatic and reversible. The nozzle angle is 20°. The moving blade is symmetric, travels at optimum velocity, and assumed to be frictionless. It is also assumed that there is neither expansion nor contraction of the steam flow through the blade passage. Draw the velocity diagram and calculate (a) the blade efficiency and (b) the stage efficiency.

Explain using an example why computing lift ratio is better in assessing soundness of an association rule than just using support for the products associated in the rule or confidence in the rule. What is the practical significance of lift ratio less than 1?

A heat exchanger with one body and eight pipe passes is designed. Water flows from the exhaust gas pipes as cold fluid by the body as cold fluid. Exhaust gas to the system at 210 ° C
and entering at a temperature of 140 ° C
The heat transfer coefficient is 392 W / m2K. On the other hand, water enters 16 iron (k = 38 W / mK) pipes with an inner diameter and outer diameter of 32 mm and 36 mm, respectively, at a temperature of 600 cm / s at 40 ° C and exiting at a temperature of 80 ° C. According to this
a.) Find the flow rate of the exhaust gas.
b.) Find the total heat transfer area.
c.) Calculate the pipe length for one pass.
(The properties of the water will be taken from the table. The air table will be used for the exhaust gas.)

A vertical axis cylinder 0.075m² in cross sectional area is open to the atmosphere at one end and closed at the other by a piston which supports a mass of 85 kg. the piston is supported by compressed air. 5.46kJ of heat is transferred to the air and the piston lifts the mass through 55cm. What is the increase in internal energy, U, during the process? Draw the path of the process on a PV diagram.

P_atmos= 1.03 bar Ans=0.75 kJ

The temperature and pressure of the steam at the inlet of a high pressure turbine is 500 ° C, respectively. It is 12 MPa and 300 ° C and 3MPa at its outlet. If the mass flow of steam is 400 kg / h, how much is the isentropic efficiency of the turbine?

With increases in obesity rates over the past several decades, health care providers have become concerned about the effects of obesity on health. As a health psychologist, you are interested in people’s perceptions and responses to food as this might influence obesity. You are curious if people that are impulsive or have difficult with impulse control are more likely to be obese and if they perceive sweet, high calorie foods as being more desirable than the general population. Given this, you screen a group of participants and recruit participants (n=20) that have high impulsivity scores (that is, they are more impulsive). From your sample, you collect participant’s weight and scores on the Food Perception Inventory (FPI) which measures individual’s preference for high calorie foods. For obesity, you know the national mean (168) and standard deviation (26.38), but you only know the population mean (103) for the FPI. Using the data below, answer the following questions:

Questions:

1. Calculate a one sample test for Weight and report the result

2. What is your decision for Weight (how will you determine if this sample is unique or rare)? Interpret your result

3. Calculate a one sample test for FPI and report the result

4. What is your decision for FPI? Interpret your result

The diameter of the discharge and suction pipe of a boiler feed pump is 4 inches and 6 inches, respectively. The water delivered is 250 GPM and the temperature is 60 F. The discharge pressure near the pump is 90 psig and the suction is 12 in.hg vacuum. Find the total dynamic head if the discharge gage is located 3 ft above pump centerline and the vacuum gage connection to the suction pipe is 2 feet below the center of the pump. Assume that the head necessary to overcome the frictional resistance through the pump is 2.20 feet.
