Steam powerplant produces 200 MW power. Saturated steam exits boiler at 3MPa pressure. Turbine exits 10kPa pressure. Isotropic efficiency of turbine is 85% and for the pump is 80%...a)show cycle on T-S diagram. b) calculate mass flow rate of steam. c) determine heat transfer rates at boiler and condencer in Mega watts. d) Determine cycle efficiency . e) determine mass flow rate of the condencer cooling water in kg/h if water enters at 15 degrees celcious and exits 25 degrees celcious.
Calculate the velocity v of the collar as it hits the stop at B if it is elevated from rest at A by the action of the constant 40-N force in the cord. The cord is guided by the small fixed pulleys.
Neglecting the mass of the rod and the effect of friction, determine the radial and transverse components of the velocity of the collar when r = 0.5 m.
the triangular plate rotates about a fixed axis through point o with the angular properties indicated determine the
