1a) Superheated steam is expanded isentropically from 1000 psia and a temperature of 900 F to saturated vapor. What is the change in specific enthalpy in BTU/lbm?

1b) Steam expands isentropically in a turbine from 500 psia and 1000 F to 14.7 psia. What is the difference in specific enthalpy, in BTU/lbm, between the initial and final conditions.?

A steam engine takes in superheated steam at 270 degree Celsius, and discharges condensed steam from its cylinder at 50 degree Celsius. The engine takes 50 kJ heat from the hot steam per cycle and does 15 kJ of work per cycle. (a) Whats the efficiency of the engine? (b) If someone claims that 60 kJ heat were taken in per cycle by another engine operating at these same temperatures and the engine can generate 30kJ work per cycle, do...

1a. The relative humdity outdoor is 70% and the outdoor temperature is 90 degree F what is the actual partial pressure of water vapor in the air 1b. Humidty ratio (w) is the ratio of the mass of the water (Mw) to the mass of dry air (Mw) note that two partial pressures sum to the total pressure (P =Pa + Pv) derive the equation w = 0.622Pv / (P-Pv). Use the ideal gas equation for mass 1c. Solve for...
