Use the sample data to construct an 80% confidence interval estimate of standard deviation of the duration times of game play. Assume that this sample was obtained from a population witha normal dis
Then a valve is opened and the air flows out isothermally until the pressure in the tank is 100 kPa. Find the amount of heat transferred during this process.
If the power required to operate the compressor is -155kW, calculate the pressure of the air as it exits the compressor (P2a) [bars]. Calculate the heat transfer rate from the compressor to the cooli
If the convection heat transfer coefficient on the inner surface of the pipe is h= 65 W/m^2*K, write the governing DE and express the Boundary Conditions on the inner and outer surfaces of the pipe
