-At sea level, a pressure gauge on a closed rigid tank reads 20.0 psi. The tank is moved to a location where the atmospheric pressure is 13.00 psi. What is the gauge pressure (psi) for the tank at this new location?
- A temperature change of 26.0 °F is equivalent to what in C
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
