GATE Mechanical Engineering (ME) 2016 Shift 1 Solved Paper

An inverted U-tube manometer is used to measure the pressure difference between two pipes A and B, as shown in the figure. Pipe A is carrying oil (specific gravity = 0.8) and pipe B is carrying water. The densities of air and water are 1.16 kg/m3 and 1000 kg/m3, respectively. The magnitude of pressure difference between pipes A and B is __________ kPa.
Acceleration due to gravity g = 10 m/s2.
