1. An insulated air compressor with an isentropic efficiency of 78.0% compresses air from 0.100 MPa, 290. K to 10.0 MPa. Use the gas tables to determine the power required per unit mass flow rate and the exit air temperature.
2. Use the gas tables (Table C.16a) to determine the final temperature and the minimum possible power required to compress 3.00 lbm/s of air from 14.7 psia, 40.0°F to 10.0 atm. in a steady flow, adiabatic process.
"Fuel energy" is available at 2000 F at a local power plant. What is the maximum work that can be produced for each BTU of fuel energy if it is winter and the surroundings are at 40 ¯F ? If this work is used to maintain a residence at 80 F, how much ..
