Abstract

The research aim is to develop an electronic mechanism to determine the discharge coefficient of a nozzle located at the bottom of a tank by using a digital electronic circuit to control the flow and discharge of water. The circuit display the volume of the water in the decimal numbers and controls the volume of the water in the tank. Therefore, when the water level below a pre-selected volume, the water pump works, when the water reaches another pre-selected value, the pump stops working. We measured the discharge coefficient of the nozzle by measuring the time required to discharge the same amount of water between each two successive levels of the eight levels specified in the tank. Volumetric water discharge rate and average discharge speed were calculated. The coefficient  was calculated by applying the relationship between the average discharge speed and the theoretical speed. The average value was 0.66
