1. Use the generalized charts to calculate the heat transfer rate required to cool 7.00 lbm/s of argon gas from 500.°F, 2000. psia to 300.°F in a steady flow, constant pressure heat exchanger. Assume the specific heats of argon are constant over this temperature range.
2. Methane is throttled adiabatically with negligible velocity change from 1500. psia, 70.0°F to atmospheric pressure.
Assuming constant specific heats and using the generalized charts, determine the exit temperature.
