Under normal operation, a dairy plant requires 4 kg/s of saturated steam at 2 MPa, which is extracted from the turbine of a cogeneration plant. Steam enters the turbine at 8 MPa and 500 ºC at a rate of 11 kg/s and leaves at 20 kPa. The extracted steam leaves the process heater as a saturated liquid and mixes with the feedwater at the constant pressure. The mixture is then pumped to the boiler pressure. Determine. (a) the rate of process heat supplied, (b) the net power output and utilization factor for this operating condition, (c) the maximum process heat that this cogeneration plant can supply, (d) the net power output when there is no need for process heat.
Please reference all tables you use. Thanks.

A 10 kg steam initially at 2 MPa saturated vapor is inside an
insulated piston cylinder. The cylinder has a bottom valve. As this
valve opens, steam at 800 kPa and 200C exits while the steam inside
the tank has 400kPa saturated vapor. Find the exit mass of steam
from the cylinder in kg.

Steam is generated in the boiler of a cogeneration plant at 4
MPa and 480 °C with a rate of 6 kg/s . The plant is to produce
power while meeting the process steam requirements for a certain
industrial application. One-third of the steam leaving the boiler
is throttled to a pressure of 820 kPa then routed to the process
heater. The rest of the steam is expanded in an isentropic turbine
to a pressure of 820 kPa and is...

A manufacturing facility requires saturated steam at 120°C at a
rate of 1.2 kg/min. Design an electric steam boiler for this
purpose under these constraints: • The boiler will be in
cylindrical shape with a height-to diameter ratio of 1.5. The
boiler can be horizontal or vertical. • A commercially available
plug-in type electrical heating element made of mechanically
polished stainless steel will be used. The diameter of the heater
can be between 0.5 cm and 3 cm. Also, the...
