Question 1

A pipe placed vertical on a level ground is used for flow measurement. If the flow is Laminar, the shear stress is maximum at the wall and this can be justified by

Question 2

1.80 m wide and 5 m long plate moves through a stationary air of density 1.22 kg/m3 and viscosity 1.8×10-4 Poise at a velocity of 1.75 m/s parallel to its length. The drag force on one side of the plate assuming turbulent flow conditions is_______?

Question 3

For a steady flow, the velocity field is . The magnitude of the acceleration of a particle at (1, -1) is

Question 4

The velocity of fluid 2.234 m/s having a viscosity 0.023 Pa.s with density 2.345 is measured at a distance of 95 mm from the boundary. Find the shear stress at the boundary?

Question 5

Water flows through a smooth circular pipe of diameter D and length L because of a pressure difference P across the length. The volume flow rate is Q and Reynolds number 103 . If the pressure difference is increased to 4 P the volume flow rate will be

Question 6

A 0.20 m diameter pipe 20 km long transports oil at a flow rate of 0.01 m3/s. Calculate power required to maintain flow if dynamic viscosity and density of oil is 0.08 Pa.s and 900 kg/m3m respectively
