Question

Pressure is applied from a gas cylinder to one side of a U-tube manometer with constant internal diameter “D", as shown below. The manometer is filled with fresh water (density = 999 kg/m3) and upon application of the pressure, the water column on one side rises by 4.00 cm relative to the other. Draw and label a free-body diagram representing the forces in the manometer. Calculate the pressure above atmospheric pressure applied by the gas.

Answer 1

P = 39200.76

Step-by-step explanation:

formula is:

P = pgh

P = pressure

p = density of fluid

g = acceleration due to gravity ( 9.81 m/s2 for earth)

h = height above the point we are looking for

P = pgh

P = 999x9.81x4

P = 39200.76
