Find exit area of the nozzle if pressure of steam is given
steam is accelerated by a nozzle from a low velocity to a velocity of 280 m/s at a rate of 2.5 kg/s. if the temperature and pressure of the steam at the nozzle exit at 400 degrees celcius and 2 MPa, the exit area of the nozzle is?

A hydraulic power generation (turbine-generator) plant is installed at a site 200 m below the free surface of a large water reservoir that can supply water at a rate of 3800 kg/s steadily.
What are the sources of error in your system? How can you minimize the experimental error? How would you modify this system to determine the specifi heat of a solid?
On an overflow structure of 50 degrees slope the water depth (measured normal to the surface of the structure) is 1.2 m (4 ft) and the streamlines are essentially straight and parallel.
Account for variation of specific heats with temperature and model the engine as a dual cycle. Determine the amount of heat supplied per cylinder.
If the temperature and pressure of the steam at the nozzle exit at 400 degrees celcius and 2 MPa, the exit area of the nozzle is?
Determine (a) the heat transfer from the compressor an (b) the volume flow rate of the refrigerant at the compressor inlet. Ignore changes in kinetic and potential energy for your calculation.
Determine (a) the electric power required (kW) to drive the pump if friction losses are neglected; and (b) the average velocity (m/s) of the water if a 20 cm diameter (ID) pipe is used.
A well insulated, thin-walled, double-pipe, counter-flow heat exchanger is to be used to cool oil. Determine the rate of heat transfer in the heat exchanger and the exit temperature of water.
A well insulated, thin-walled, double-pipe, counter-flow heat exchanger is to be used to cool oil [Cp = 2.20 kJ/(kg C)] from 150 C to 40 C at a rate of 2 kg/s by water.
