The water in a tank is pressurized by air, and the pressure is measured by a multifluid
manometer as shown in the Figure Qla with fluid levels of: h1=0.4 m, h2=0.5 m and
h3=0.6 m.
Take the densities of water, oil and mercury to be 1000 kg/m³, 850 kg/m³ and 13600
kg/m³ respectively.

Figure Q1a
a) What is the gauge pressure at point 1, the surface of the water in the tank?
b) In deriving the Darcy-Weisbach equation it was found that there is a direct
relationship between the pressure drop experienced due to friction along a
pipe with its length. Using dimensional analysis determine an expression for
this pressure drop assuming that it is also a function of the pipe diameter in
inches, fluid density and velocity.
c) Assuming incompressible flow and that complete mixing occurs between the
two inflows shown in Figure Q1c before the mixture discharges from the pipe
at D. Determine for the fluid at D:
i-
The mass flow rate
The density
The velocity

Referring to Figure , how much water is stored after 20 minutes in each of the tanks? How long will it take to fill the tanks completely, provided that the volume of tank is 24 m3 and tank (a) has a volume of 36 m3 ? Assume the density of water is 1000 kg/m3 .
How much water is stored after 5 minutes in each of the tanks shown? How long will it take to fill the tanks completely provided that the volume of each tank is 12 m3 ? Assume the density of water is 1000 kg/ m3 .
