Select the drawing that best represents the ideal and real Total Energy Lines (EL) and the ideal and real Hydraulic Grade Lines (HGL) across a Venturi meter.

Select all the TRUE responses: (Note that wrong answers will result in deduction of marks to a minimum of zero marks for this question part.)

A student would like to apply Buckingham’s π theorem to investigate the relationship between frictional head loss, , and variables in a horizontal pipe of circular cross-section, such as pressure -drop , diameter , the density of the fluid , viscosity and the linear velocity of the fluid . The student has chosen and  as repeating variables. 

In the following variables, which one should NOT be chosen as another repeating variable?

Answer the following.

Match the following basic quantities to their SI Units.

Match the following derived quantities to their SI Units.

Match the physical quantity to their respective dimension where L is length, M is mass, T is time and Θ is temperature.

Pressure drop depends on four variables: the diameter of pipe , the fluid density , the fluid dynamic viscosity and the mean velocity . By applying the indicial method (Buckinham's Pi Theorem), it is obtained the dimension equation for the above variables .

Which of the following statements in terms of [M] is correct?
