A pump draws water through a 300-mm diameter cast iron pipe, 15m long from a reservoir
in which the water surface is 4.5 m higher than the pump and discharges through a 250-
mm diameter cast iron, 75 m long, to an elevated tank in which the water surface is 60 m
higher than the pump. Q=0.25 m³/s. Considering f-0.02 and the coefficients for minor
head losses (k entrance 0.5, k bend 0.35, and K exit -0.5), compute the power of the pump.

A 100 m length of a smooth horizontal pipe is attached to a large reservoir. A
attached to the end of the pipe
to pump water into the
reservoir at a volume flow rate
of 0.01 m³/s. What pressure
(gage) must the pump produce
at the pipe to generate this
flow rate? The inside diameter
of the smooth pipe is 150mm.
Dynamic Viscosity of water is
1*103 Kg/(m.s). K at the exit
of the pipe is 1.

A heavy car plunges into a lake during an accident and lands at the bottom of the lake
on its wheels as shown in figure. The door is 1.2 m high and 1 m wide, and the top edge of
the door is 8 m below the free surface of the water. Determine the hydrostatic force on the
door if it is located at the center of the door, and discuss if the driver can open the door, if
not; suggest a way for him to open it. Assume a strong person can lift 100 kg, the passenger
cabin is well-sealed so that no water leaks inside. The door can be approximated as a
vertical rectangular plate.
