The viscosity of a liquid

November 25, 2019 BILAL KHATTAK0

A.remains unaffected with change in temperature
B.decreases with increase in temperature
C.increases with increase in temperature
D.is dependent on pressure only

A plate 0.6 mm distant from a fixed plate moves at 0.24 m/s and requires a force per unit area of 1 N/m2 to maintain this speed. Thefluid viscosity of the substance between the plates in N.s/m2 is

B.2.5
C.2.5 x 10-3
D.0.4 x 103

The total energy grade line in pipe flow is a graphical representation of Bernoullis equation and represents the sum of elevation head pressure head and velocity head measured above
