Steam is supplied to a turbine at a rate of 1.00 × 106 kg/h at 500.°C and 10.0 MPa, and it exhausts to a condenser at 2.00 kPa. A single open loop regenerator is used to heat the boiler feedwater with steam extracted from the turbine at 6.00 MPa. The condensate exits the regenerator at 6.00 MPa as a saturated liquid. Neglecting the pump power, determine
a. The mass flow rate of steam extracted from the turbine.
b. The system's isentropic Rankine cycle thermal efficiency.
c. The isentropic Rankine cycle thermal efficiency of the same system without a regenerator.
d. The percent increase in thermal efficiency due to the regenerator.
It has been a while since I had calculus so I am having trouble remembering how to multiply the equations out. Can anyone do a step - by - step process?
Julie throws a ball to her friend Sarah. The ball leaves Julie's hand a distance 1.5 meters above the ground with an initial speed of 17 m/s at an angle 36 degrees; How high above the ground will the ball be when it gets to Julie
A very long, straight wire carries a current of 0.180 A. This wire is tangent to a single-turn, circular wire loop that also carries a current. The directions of the currents are such that the net magnetic field at the center of the loop is zero.
a car originally traveling at 30ms manages to brake for 5.0 seconds while traveling 125 m downhill. at that point the
Two particles are moving in opposite directions with the same speed of 0.8C , what is their relative speed?
Two crates, of mass 77 kg and 108 kg, arein contact and at rest on a horizontal surface (Fig. 4-47). A 729 Nforce is exerted on the 77 kg crate.If the coefficient of kineticfriction is 0.15, calculate the following: the force that eachcrate exerts..
A simple pendulum consists of a small object of mass m (the "bob") suspended by a cord of length l of negligible mass. A force F is applied in the horizontal direction (so F is Fi), Determine the work done by the gravitational force on the bob
Find the average speed of a ratchet moving by steps of length L through a medium where its diffusion constant is D with no backward motion, as was done in the lectures
as a helicopter carrying a crate takes off its vertical position as well as the crates is given as yt at3 where a is a
The magnetic flux through one face of a cube is +0.120Wb. a) Whatmust the total magnetic flux through the other five faces of thecube be? b) why didn't you need to know the dimensions of the cubein order to answer part (a)?
If a curve with a radius of 60 meters is properly banked for a car traveling 60 km/hr, what must the coefficient of friction be for a car on the same curve traveling 90 km/hr.
A 27 kg block slides up a hill to a height of 6.6 m. If 387 J of thermal energy are generated, how fast was the block going at the bottom of the hill?
