a)      Calculate atmospheric pressure as a head of mercury (relative density of mercury is 13.6 and atmospheric pressure is 1.01 x 105 Pa).

b)      Water with dynamic viscosity of 1.007 x 10-3 kg/ms flows along a 0.015 m diameter pipe at a velocity of 0.5 m/s. Determine if the flow is laminar, transitional or turbulent.

c)      Explain why it may be desirable to use two or more pumps operating together instead of one large pump.

d)      Compare gravity dams and arch dams considering their merits and demerits.
