Answer #1

Atmospheric pressure at sea level = 14.696 psi

Absolute pressure =Atmospheric pressure + gauge pressure

At sea level :  

Absolute pressure = 14.696 + 20 = 34.696 psi

Absolute pressure will not vary with location.

At new location :

Atmospheric pressure = 13 psi

Guage pressure = Absolute pressure - atmospheric pressure

Gauge Pressure = 34.696 - 13 = 21.696 psi.

Temperature change in degree Fahrenheit (del F) = 26

Temperature change in degree Centigrade (del C) =?

del C = del F / 1.8

del C = 26/1.8 = 14.44 C
