if the absolute pressure of a gas is 550.280 kPa, its gage pressure is ?
A.101.325kPa
b.277.280kPa
c.448.955kPa
d.651.605kPa
Gauge pressure - atmosphericpressure=absolute pressure
where atmospheric pressure varies, but standard atmospheric pressure is 101.325kPa
NEED ANSWER
whats the answer?
b
omg this was so long ago
To find the gauge pressure, subtract the atmospheric pressure from the absolute pressure.
Given:
Absolute pressure = 550.280 kPa
Standard atmospheric pressure = 101.325 kPa
Gauge pressure = Absolute pressure - Atmospheric pressure
Gauge pressure = 550.280 kPa - 101.325 kPa
Gauge pressure = 448.955 kPa
Therefore, the gage pressure is 448.955 kPa.
The correct answer is (c) 448.955 kPa.
