Water flows in a horizontal constant-area pipe; the pipe diameter is 75 mm and the average flow speed is 5 m/s. at the pipe inlet, the gage pressure is 275 kpa, and the outlet is at atmoshperic pressure. determine the head loss in the pipe

Head loss = 28.03 m

Explanation:

According to Bernoulli's theorem for fluids  we have

Applying this between the 2 given points we have

Here is the head loss that occurs

Since the pipe is horizantal we have

Applying contunity equation between the 2 sections we get

Since the cross sectional area of the both the sections is same thus the speed

is also same

Using this information in the above equation of head loss we obtain

Applying values we get
