Textbook Question
Chapter 10, Problem 16RQ
A technician takes the following readings on an R-404A refrigeration system:
Head pressure = 205 psig
Suction pressure = 30 psig
Condenser outlet temperature = 80°F
Evaporator outlet temperature = 10°F
Using the pressure/temperature chart in Figure 10.25, find the condenser subcooling and evaporator superheat amounts.

Steam is supplied to a two-stage turbine at 48 bar and 400 °C. It expands in the first
turbine until it is just dry saturated, then it is re-heated to 400 °C and expanded
through the second-stage turbine. The condenser pressure is 0.04 bar.
