Question1) A fluid at 0.7 bar occupying 0.09 m3 is compressed reversibly to a pressure of 3.5 bar according to law pvn = constant. The fluid is then heated reversibly at constant volume until pressure is 4 bar; the specific volume is then 0.5 m3/kg. A reversible expansion according to the law pv2 = constant restores the fluid to its initial state.
a. Compute the mass of the fluid present
b. Find out the value of n in the first process
c. Calculate the net work of the cycle.
Question2) In the figure below, the 20°C water and gasoline surfaces are open to atmosphere and at the same elevation. What is the height h of the third liquid in the right leg?
