Difference in heights between the pipe and Gage is 5m
Density of water is 1000kg/m3
Acceleration due to gravity 10 m/s2
Actual Pressure is nothing but the absolute pressure.
Absolute pressure= Atmospheric pressure + Gauge pressure.
(i) If the pressure is measured at the ground level
Absolute pressure = 110k Pa + 101.3 k Pa = 211.3 k Pa
[Note: Atmospheric Pressure = 101.3 k Pa]
Absolute in pressure in B = 101.3k Pa + 65k Pa= 166.3k Pa
