4. Consider a reheat–regenerative vapor power cycle with two feedwater heaters, a closed feedwater heater and an open feedwater heater. Steam enters the first turbine at 12.0 MPa, 520C and expands to 0.6 MPa. The steam is reheated to 440C before entering the second turbine, where it expands to the condenser pressure of 0.006 MPa. Steam is extracted from the first turbine at 2 MPa and fed to the closed feedwater heater. Feedwater leaves the closed heater at 200C and...

A steam power plant operates on a regenerative Rankine cycle with two feedwater heaters, one closed and one open. Steam enters the turbine at 12.5 MPa and 550ºC and exhausts to the condenser at 10 kPa. Steam is extracted from the turbine at 1 MPa for the closed feedwater heater and 0.8 MPa for the open one. The feedwater is heated to the condensation temperature of the extracted steam in the closed feedwater heater. The extracted steam leaves the closed...

Design a steam power plant that works as an ideal Regenerative Rankine cycle with 2 closed feedwater heaters cascaded backwards by selecting their extraction pressures to optimize cycle efficiency. The available steam conditions at the exit of the boiler are 3 MPa and 590 °C and the condenser pressure is 20 kPa. The steam flow rate at the inlet of the turbine is 80 kg/s. A T-s diagram for the cycle should be provided along with a table showing the...

Distillation post lab: 1-why was the temperature of the heater probe so much higher than the distillation temperature? 2-what is the same comparing separation by distillation to separation by TLC? 3-even if you heated the boiling flask until it was dry, not all the highest boiling compounds will be condensed and collected. why? 4-describe 2 ways in which the distillation set up could break and describe how to avoid that.

1. A steam powerplant operating on an ideal Rankine Cycle is operating at a boiler pressure of 5.75 MPa, steam enters the turbine at 500°C and expands to 147 kPa. If the powerplant is producing 5MW of energy find the following: a. Enthalpies at each point of the cycle 1,2,3,B b. Net work in kj/kg c. Mass flow rate of throttle steam used by the powerplant d. heat added in the boiler e. heat rejected in the condenser f. cycle...

Why are vectors essential for doing physics? There might be more than one correct answer. a.Vectors are not needed for idealized particles with zero volume, but they are needed whenever an object has volume. Since all real objects have volume, vectors are needed. b.Even though vectors are purely mathematical constructions (i.e. you will never see a vector in the real world), they add together in exactly the same way that real world phenomena add together. c.The universe has more than...
