A smooth pipe of diameter 200 mm carries water. The pressure in the pipe at section S1 (elevation:10 m) is 50 kPa. At section S2 (elevation:12 m) the pressure is 20 kPa and velocity is 2 ms-1. Density of water is 1000 kgm-3 and acceleration due to gravity is 9.8 ms-2. Which of the following is TRUE
Detailed Solution for Test: Dynamic of Fluid Flow - 3 - Question 6


Applying Bernoulli’s equation between section S1 and S2

as area is constant velocity head will be same

thus flow from S1 to S2 and head loss is 1.06 m.
