5 lb of propane is contained in a closed, rigid tank initially at 80 lbf/in^2, 110 degrees Fahrenheit. Heat transfer occurs until the final temperature in the tank is 0 degrees Fahrenheit. Kinetic and potential energy effects are negligible. Show the initial and final states on a T-v diagram and determine the amount of energy transfer by heat, in Btu.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.

Apure substance is a)-mixture of various chemical elements or compounds b)-substance that has a fixed chemical composition throughout c)-mixture that is homogeneous (such as air) d)-all the answers
