A pump delivers 2.5 liters/ second of water at 30C via a pipe of 50 mm diameter and surface roughness 0.5mm. The water is drawn from a tank maintained at atmospheric pressure and delivered to a tank that is maintained at 2 bar (gage). The pump is 1 meter above the level of water in the suction tank and the length of the suction side of the pipe is 3 m. The delivery tank is located 2 meters above the pump and the length of the delivery side of the pipe is 17 m. The suction side has a foot value (minor loss coefficient = 7), a gate value (minor loss coefficient = 0.5) and an 90 elbow bend (minor loss coefficient = 0.5). The delivery side has two 90 elbow bends (minor loss coefficient = 0.5). The delivery side exits into the delivery tank with minor loss coefficient is 1.0. Kinematic viscosity is u = 0.8 x 10^{-6} m^2/s

What's the head (in m) due to the pressure difference between the supply and delivery tanks?

What's the total static head (in m)? Total static head is sum of pressure head and elevation head.

What's the velocity (in m/s) of water in the pipe?

What's the Reynold's number?

The flow in the pipe is turbulent. True or False?
