1. The steady-flow energy-equation (SFEE) can be applied to many open-system applications. Start from the basic SFEE: a. What is the total heat rate that is needed for a boiler, in terms of enthalpies and mass flow rate? b. How can the compressor work be calculated, in terms of enthalpies and mass flow rate? c. R134a refrigerant enters a compression cycle at 165 kPa and -12 °C, then leaving the compressor at 370 kPa and 45 °C. If the closed-loop mass flow rate is 0.06 kg/s, how much power is needed to drive a compressor with an efficiency is 80%.
