Water is the working fluid in a vapor power cycle with reheat superheat and reheat. superheated steam enters the first turbine stage at 8 MPa, 480 C and expands to 0.7 MPa. it then is reheated to 480 C before entering the second turbine stage, where it expands to th condenser pressure of 8 KPa. The mass flow rate of steam enter ...continues
Steam @ 10 MPa, 600 degrees celcius enters the first-stage turbine of an ideal Rankine cycle with reheat. The steam leaving the reheat section of the steam generator is @ 500 degrees celcius, and the condensor pressure is 5 kPa. If the quality at the exit of the second-stage turbine is 90%, determine the cycle thermal efficien ...continues

Determine the final velocity, in ft/s, if the kinetic energy of the object decreases by 100 ft*lbf
An object whose mass is 1 lb has a velocity of 100 ft/s. How would I determine the final velocity, in ft/s, if the kinetic energy of the object decreases by 100 ft*lbf? What would be the change in elevation, in ft. associated with the 100 ft*lbf change in potential energy if g=32.0 ft/s^2?
12-V automotive storage battery is charged with a constant current
A 12-V automotive storage battery is charged with a constant current of 2 amp for 24 hr. If electricity costs $0.08 per kW*h, how would I determine the cost of recharging the battery?
