Question 1

The maximum velocity of a one-dimensional incompressible fully developed viscous flow, between two fixed parallel plates, is 6ms^-1. The mean velocity (in ms^-1) of the flow is

Question 2

For steady, fully developed flow inside a straight pipe of diameter D neglecting gravity effects, the pressure drop Δp over a length L and the wall shear stress

are related by

Question 3

A centrifugal pump is required to pump water to an open water tank situated 4 km away from the location of the pump through a pipe of diameter 0.2 m having Darcy’s friction factor of 0.01. The average speed of water in the pipe is 2 m/s. if it is maintain a constant head of 5 m in the tank, neglecting other minor losses, the absolute discharge pressure at the pump exit is

Question 4

For a fully developed flow or water in a pipe having diameter 10 cm, velocity 0.1 m/s and kinematic viscosity $Description: D:\GradeStack Courses\GATE Tests (Sent by Ravi)\GATE-ME-2014-Set-1_files\image146.png$ , the value of Darcy friction factor is ____

Question 5

Velocity vector of a flow field is given a $Description: D:\GradeStack Courses\GATE Tests (Sent by Ravi)\GATE EC-ME-17-Mar\GATE-ME-2010_files\image070.png$ The vorticity vector at (1,1,1) is

Question 6

For a fluid flow through a divergent pipe of length L having inlet and outlet radii and R1 and R2 respectively and a constant flow rate of Q, assuming the velocity to be axial and uniform at any cross section, the acceleration at the exit is
