The flow in a pipe is neither laminar nor turbulent when Reynold number is
A tank is filled by three pipes with uniform flow. The first two pipes operating simultaneously fill the tank in the same time during which the tank is filled by the third pipe alone. The second pipe fills the tank 5 hours faster than the first pipe and 4 hours slower than the third pipe. The time required by the first pipe is:
A water tank with 64-gallon capacity is filled by pipe A and emptied by pipe B. If the rate of water flow through pipe A is 2 gallons per hour, how many gallons per hour should flow through pipe B so that when both pipes are open, the initially empty tank shold be full in exactly 96 hours?
Transition from laminar flow to turbulent flow in fluid flow through a pipe does not depend upon the
For turbulent fluid flow in pipe, the expression for Prandtl one seventh power law is (where, r = pipe radius, x = distance).
The distance y from pipe boundary, at which the point velocity is equal to average velocity for turbulent flow, is (where R is radius of pipe)
Transition length for turbulent flow in smooth pipe is equal to __________ times the pipe diameter.
In turbulent flow, a rough pipe has the same friction factor as a smooth pipe
For turbulent flow in smooth circular pipe, the velocity distribution is a function of the distance 'd' measured from the wall of the pipe and the friction velocity 'v', and it follows a __________ relationship.
Water flows into an empty 64-gallon drum through pipe A and flows out through pipe B. If the rate of flow through A is 2 gallons/hour, how many gallons per hour must flow out through pipe B so that the drum is full in exactly 96 hours?
