List of top Civil Engineering Questions on Fluid Mechanics asked in AP PGECET

A flat plate of 0.15 m\(^2\) is pulled at 20 cm/s relative to another plate, fixed at a distance of 0.02 cm from it with a fluid having \( \mu = 0.0014 \, \text{Ns/m}^2 \) separating them. The power required to maintain the motion is ...........
The flow of a liquid at constant rate in a conically tapered pipe is classified as ...........
Magnitude of the component of velocity at point (1,1) for a stream function \( \Psi = x^2 - y^2 \) is equal to ............
A wide channel is 1 m deep and has a velocity of flow \( V = 2.13 \, \text{m/s} \). If a disturbance is caused, an elementary wave can travel upstream with a velocity of ............
The maximum diameter that a capillary tube can have to ensure that a capillary rise of at least 6 mm is achieved when the tube is dipped into a body of liquid with surface tension \( = 0.08 \, \text{N/m} \) and density \( = 900 \, \text{kg/m}^3 \) is ...........
A sphere of 150 mm diameter is held in equilibrium by a vertical air stream of velocity 15 m/s. If the density of air is \( 1.225 \, \text{kg/m}^3 \) and the coefficient of drag is 0.43, the weight of the sphere is ...........
A 75 mm diameter pipe of 500 m length operates under a head of 60 m at its inlet. If a nozzle is fitted at its outlet, then for most efficient conditions, the velocity of flow from the nozzle (with \( C_v = 1 \)) is .........
