I will pay for the following article Water Pump. The work is to be 8 pages with three to five sources, with in-text citations and a reference page. The impeller was responsible for the accumulation of the pressure drop that led to the formation of the vapour bubbles, and the NPSH was greater than zero and was flow rate dependent.

Water pumps are used in pumping of water from one point to another. This water can be pumped to residential areas or to farms in order to be used for irrigation. The most common the type of pump used is the centrifugal pump that utilizes the energy supplied by a motor in order to suck water through the impeller and then it discharges it through the exit. When doing so, the head is built in the pump in order to discharge the water to greater heights. This, which is build up, is due to the energy supplied by the motor.

Here, H represents the pump head, is the head losses, which is attributed to the loss of energy in the walls of the pump, represents the pressure difference between the suction side and the discharge side andrepresents the velocities of the fluid at the suction and the discharge side of the pump. 1

1. To analyse the pump’s characteristic curves of the pump at varied constant speeds. the pump head. water horsepower. shaft horsepower. the pump efficiency. and the Net Positive Suction Head (NPSH).

The system utilised in this experiment was an educational pump setup made by the Turbine Technologies. The flow rates were controlled by the pump speed, inlet valve setting, choice of impeller, and the outlet valve setting.

The outlet and inlet valves also allowed the simulation of varied pressure conditions on the pump. this entailed the partially closing of the outlet valve creating similar effects to that of longer length or several turns of pipes on the pump outlet. The fluid reservoir was at lower elevation as compared to the pump. therefore, it meant that gravity could not feed the measured water into the pump, instead the sucked up the water, that is, also known as the negative pressure head.
