Abstract

This project report is writen about A design and construct experiment roughness inpipe the measurement two point about 1 metre pressure head arc show in he tube which comprise the manometer panel the scale hind these tube directly measures the water levels. The pressure differencetwo point in two ducc calculate by the thory of Bernoulli and open moody diagram values roughness by make experiment pipe dimeter 43 millimetre and water flow rate according varied from 74 LPM
