4. Consider a top secret military power supply for arctic environment operations that will produce electrical power from the soldier's body heat. Model this power supply as a Carnot-cycle heat ENGINE that uses R-22 as its working fluid. The boiler operates at 30°C and converts saturated liquid into saturated vapor. The condenser operates at -5ºC. a. Show the cycle on a T-S (temperature vs. specific entropy) diagram relative to the 2-phase region and indicate, with arrows, the directions of working fluid flow. b. Determine the required operating pressures of the boiler and condenser (in kPa). (Answers: 1191.9 kPa and 421.3 kPa, respectively) c. Determine the quality of the R-22 at the entrance and exit of the condenser. (Answers: 0.9394 and 0.1878, respectively)

Expert Solution
Step 1: Introduction

To draw temperature entropy drawing R 22 fluid, to calculate operating pressures and quality at entrance and exit of condenser

with the boiler operating temperature as

t subscript 1 space equals 30 space C,

the operating temperature of condenser is t subscript 2 space equals negative 5 C
