Question 1
At a point A in a pipe line carrying water, the diameter is 1 m, the pressure 98 KPa and the velocity 1 m/s. At a point B, 2 m higher than A, the diameter is 0.5 m and the pressure 20 KPa. The direction of flow would be
Question 2
The velocity distribution for flow over a flat plate is given by U = (3/4)y-y2 in which u is the velocity in m/s at a distance y meter above the plate. If the dynamic velocity of the fluid is 10 poise, then the shear stress at 0.2 m is
Question 3
The transition Reynolds number for flow over a flat plate is 5 x 105. What is the distance from the leading edge at which transition will occur for flow of water with a uniform velocity of 1m/s? (For water, the kinematic viscosity, v = 0.858 x 10-6 m2/s)
Question 4
Which of the following is the correct definition of the Reynolds number?
Where p = fluid density, U = velocity, L = Length and 
= kinematic viscosity
Question 5
The Moody diagram is shown in fig. The friction factor for turbulent flow in a smooth pipe is given by curve
