A pump draws water from reservoir A with water surface at elevation 0 to reservoir B at elevation 240m. The loss of head from A to the suction side(point 1) of the pump (Elevation-20m) is 3 times the velocity head in the 150mm pipe between A and point 1, and the loss of head from point 2(discharge side of the pump) to B is 15 times the velocity head in the 100mm pipe between point 2 to point B. When the discharge is 20L/s, compute the following: a. Power output of the pump in kW b. Pressure head at point 1 c. Pressure head at point 2

Fluid Pressure

The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.

Gauge Pressure

Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
