Q. Bloom’s
Question Marks COs
No Level
a) A town has a 1-million-gallon storage capacity water tower. If the density of water is 1000
kg/m3 and local acceleration of gravity is 9.81 m/s2, what is the force, in N, the structural 4
base must provide to support the water in the tower?
1. CO1 L1
b) A closed system consists of 0.5 kmol of ammonia occupying a volume of 6 m3. Determine
(a) the weight of the system, in N, and (b) the specific volume, in m 3/kmol and m3/kg. Let 6
g= 9.81 m/s2. (MNH3= 17.031 kg/kmol )
Three kg of gas in a piston–cylinder assembly undergo a process during which the relationship
2. between pressure and specific volume is pv0.5= constant. The process begins with P1 = 250 kPa 10 CO3 L5
and V1 = 1.5 m3 and ends with 2 = 100 kPa. Determine the final specific volume, in m3/kg. Plot
the process on a graph of pressure versus specific volume.

3. CO4 L3
Complete the given sketch below. Write the relation between, absolute pressure, gage pressure,
vacuum pressure and atmospheric pressure.
A vacuum gage connected to a chamber reads 35 kpa at a location where the atmospheric 2
pressure is 100 kpa. Determine the absolute pressure in the chamber.
a) For the above sketch, what would be the pressure at point 1 at the
bottom of the tank. Write an expression if fluid in the container maintain
different densities and same densities. 5
CO3,
4. b) Consider two identical fans, one at sea level and the other on top of L3
a high mountain, running at identical speeds. How would you compare 4
(a) the volume flow rates and (b) the mass flow rates of these two fans? 5
