An ideal Rankine cycle uses water as a working fluid, which circulates at a rate of 80 kg/s. The boiler pressure is 6 Mpa, and the condenser pressure is 10 kpa. The water enters the turbine at 600 C and leaves the condenser as a saturated liquid. Assume that the heat is transferred to the working fluid in the boiler from a reservoir at 1400 K and that the fluid in the condenser rejects heat to the surroundings at 25 C. Calculate the following quatities: (a) The power required to operate the pump; (b) The heat-input rate to the water in the boiler; (c) The power developed by the turbine.
The process of apparent change in frequency (or wavelength) of the light because of relative motion among the source of light and the observer is known as Doppler's effect.
What is curvilinear motion? Basically, it's any motion that's produced or bounded by curved -- as opposed to straight -- lines. In high school, curvilinear motion is usually
A medium is known as denser if the velocity of ray in that phase is fewer than the speed of the wave in other phase. In comparison to air velocity of sound is main in water,
Two travelling sinusoidal waves are described by the wave functions Y 1 = 55.00 sin [π (4.00 x - 1200 t )] Y 2 =55.00 sin [π (4.00 x - 1200 t - 0.250)] Where x ,
