Determine entropy change from initial state to final state
A constant-volume tank contains 10 lbm of ammonia initially at 30 lbf/in^2 and 80(deg)F (539.67(deg)R). The ammonia is then cooled until its pressure drops to 10 lbf/in^2. Determine its entropy change from the initial state to the final state.

What minimum coefficient of friction is necessary between the wall and the riders in order for there to be no tendency to slide down the wall?
A solid aluminium sphere of emissivityε is initially at an elevated temperature and is cooled by placing it in chamber. The walls of the chamber are maintained at a lower temperature and a cold gas is circulated through the chamber.
A water cooled spherical object of diameter 10 mm and emissivity 0.9 is maintained at 4000C. What is the net transfer rate from the oven walls to the object?
Determine the total electrical work the heat pump can consume on that day. If the heat pump consumes 6.6kW of power while operating, how long the heat pump ran on that day?

Assume that the paired data came from a population that is normally distributed. Using a 0.05 significance level find the mean value of the differences d for the paired sample data, the standard deviation of the differences d for the paried sample
Listed below are actual high temperatures and high temperatures that were forcast one day earlier. Construct a 95% confidence interval estimate of the mean difference between actual and forcast temperatures. Interpret the resulting confidence inte
