Natural gas is stored in a spherical tank at a temperature of 10°C. At a given initial time, the pressure in the tank is 100 kPa gage, and the atmospheric pressure is 100 kPa absolute. Sometime later, after considerably more gas is pumped into the tank, the pressure in the tank is 200 kPa gage, and the temperature is still 10°C. What will be the ratio of the mass of natural gas in the tank when p = 200 kPa gage to that when the pressure was 100 kPa gage? 8. At a temperature of 100°C and an absolute pressure of 5 atmospheres, what is the ratio of the density of water to the density of air, ρw/ρa?
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.

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:
