Question

The pressure gauge on the steam condenser for a turbine indicates 66.5 mm Hg of vacuum. The barometer reading for the local atmospheric pressure is 755 mm Hg. What is the pressure in the condenser in psia g

Answer 1

Answer:

13.32

Explanation:

first we convert mmhg to psi

Pcond=-66.5/51.71=-1.28psi

Patm=755/51.71=14.6psi

Pabs=Pgauge+Patm

Pabs=-1.28+14.6

Pabs=13.32psiag
