How much heat transfer should we have
Expected delivery within 24 Hours
It is to be pumped to 500 kPa and fed to a pipeline at the rate of 0.5 kg/s. How much power input is required for the pump, assuming it to be reversible?
If the initial mass was 1 kg, how much mass is left in the tank and what is the turbine work, assuming a reversible process?
A steam turbine in a power plant receives 5 kg/s steam at 3000 kPa, 500oC. Find the two exit temperatures and the turbine power output.
A small turbine delivers 1.5 MW and is supplied with steam at 700oC, 2 MPa. Find the specific turbine work and the heat transfer in the heat exchanger.
We have a heat source at constant 500oC. If the process should be reversible, how much heat transfer should we have?
Find the final temperature and mass, assuming a reversible adiabatic process for the air remaining inside the tank.
If the process is adiabatic and reversible, find the final mass in the tank and the turbine work output.
A supply line is supplied by an insulated compressor that takes in R-134a at 5oC. Calculate the total work input to the compressor to charge the tank.
To increase the work out of a turbine for given inlet and exit pressures, how should the inlet state be changed?
