Consider a water storage tank with inlet and outlet streams that
can be independently adjusted. The storage tank has a
cross-sectional area of 100 ft2. Initially, the flow in
is equal to the flow out, which is 5 ft3/min. The
initial height of water in the tank is 4 ft and the height of the
tank is 10 ft. At t = 0 a ramp increase in the inlet flowrate is
made, so that Fi(t) = 5 + 0.25 t...

A horizontal tapering pipe bend of 45 degree, has inlet diameter
of 600 mm and outlet diameter of 300 mm. The pressure at its inlet
end is 150 KPa and discharge through the bend is 0.5 m3/s.
Determine the magnitude of the force exerted by the water on the
bend.

Consider a pipe (diameter of 50 mm) with air flowing through it.
The inlet conditions are: Mach 3; total pressure = 1000 kPa and 550
K. The friction coefficient (f) is 0.004. The exit Mach number
decreases with the length of the pipe. Assume adiabatic, steady
flow.

Steam enters a turbine at a velocity of 200 m/s. The inlet
conditions of the steam are at 4000 kPA and 500°C. The diameter of
the inlet pipe is 50 mm. The outlet conditions of the steam are 80
kPa and a quality of 1.0. The diameter of the outlet pipe is 250
mm. Determine the turbine power output in kJ/s assuming the kinetic
energy change and potential energy change are both negligible.

A steam turbine operates with steam at inlet conditions of 3.5
MPa and 3500 C. The exit stream leave the turbine is at 0.8 MPa and
is known to contain a mixture of saturated vapor and liquid. The
steam rate through the turbine is 1000 kg/h. A (negligible)
fraction of exit stream is bled through a throttle valve to 0.10
MPa and is found to be 1250 C. The measured output of the turbine
is 100 kW.
a) Determine the...
