please solve quickly. Waste heat from a chemical reactor is to run a boiler in a Rankine power cycle. The working fluid in the cycle is water. The boiler generates steam which exits at 300 psia and 1200°F. The condenser in the cycle runs at 3 psia, producing a saturated liquid. The turbine and the pump can be considered adiabatic and reversible. Assume the pump is driven by the turbinea.

a) Calculate the net work produced by the cycle, in Btu/lbm of steam. Wt=-524btu/lbm
b) What is the thermal efficiency of the process?
c) What percent of the heat entering the boiler is discharged from the condenser?

d) Carefully sketch a T-S diagram of this cycle, showing the temperatures of the streams between the processing units, and their locations relative to the phase boundaries. Label all axes.

A steam power plant operates with a boiler that is heated from a heat source at 457 °C and produces 450 ton/hr. of steam. The steam leaves the boiler at 425 °C and 4 MPa. The steam reaches a turbine at 375 °C and 3 MPa and leaves it at 50 kPa with 4% liquid water. This mixture is flown into a condenser that rejects the heat into a river at 17 °C. Water leaves the condenser at 50 kPa...

You are planning to buy a heat exchanger to recover 1.3 MMBtu/hr of waste heat from a process into a feed stream. Currently you pay $10/MMBtu for steam to heat up this feed stream. You can install a carbon steel shell and tube exchanger (U-tube type, with a heat transfer area of 150 m2) into a tight spot between two other pieces of equipment. This exchanger costs 199,757$ and will need to be replaced in 10 years, but will have...

a) Estimate the decay heat load from a 3000 MWt reactor at one day, one week, one month, and one year after shutdown from a 2-year run. b) Estimate the rate of heat up in a reactor core that has lost all of its coolant. Consider the decay heat loads found above. Assume the heat capacitance of the dry reactor core is 16,500 Btu/°F.

Please show simple calculations: Problem: Computer cooling is required to remove the waste heat produced by computer components, to keep components within permissible operating temperature limits. Components that are susceptible to temporary malfunction or permanent failure if overheated include integrated circuits such as Central processing units (CPUs), chipset, graphics cards, and hard disk drives. Cooling may be designed to reduce the ambient temperature within the case of a computer, such as by exhausting hot air, or to cool a single...
