Chapter $6$: HW $6$ On$-$Paper Assignment

# $25$

You are given the following refrigeration cycle with the following states knowing that the mass flow rate is $q,3\mathrm{.}5k\frac{g}{s}$ :

a$.$ State $1$: Before the compressor

i$.$ Sat. Vapor

ii$.P=140$kPa

b$.$ State $2$: After compressor

i$.T=q,$ C

ii$.P=800$kPa

c$.$ State $3$: After the condenser

i$.P=800$kPa

ii$.$ Sat. liquid

d$.$ State $4$: After expansion valve

i$.P=P1$

Determine:
