Question 3
The circular water pipes shown in the sketch are following full. The velocity of flow (in m/s) in the branch pipe “R” is
Question 4
Two pipes of same length L/2 and diameters d and 2d respectively are connected in series. The diameter of an equivalent pipe of the length L is
Question 5
A single pipe of length 1500 m and diameter 60 cm connects two reservoirs having a difference of 20 m in their water levels. The pipe is to be replaced by two pipes of the same lengthy and equal diameter d to convey 25% more discharge under the same head loss. If the friction factor is assumed to be the same for all the pipes, the value of d is approximately equal to which of the following options?
Question 6
For air flow over a flat plate, velocity (U) and boundary layer thickness (δ) can be expressed respectively, as
If the free stream velocity is 2m/s, and air has kinematic viscosity of 1.5×10-5 m2/s and density of 1.23 kg/m3, the wall shear stress at x = 1m, is
If the free stream velocity is 2m/s, and air has kinematic viscosity of 1.5×10-5 m2/s and density of 1.23 kg/m3, the wall shear stress at x = 1m, is
