1. The problem statement, all variables and given/known data Can any one help with this particular question Using a steam power plant that operates on a simple rankine cycle and has a net power output of 45MW. Steam enters the turbine at 70 bar and 500 degrees c and is cooled in the condenser at a pressure of 110kPa by running cooling water, from a lake through tubes to the condenser at a rate of 2000kg/sec. Determine: The temperature rise of the cooling water? 3. The attempt at a solution I have calculated the thermal efficiency of the cycle to be at 39% and the mass flow rate of steam to be at 36 kg/sec. Should i be using the equation Q=m.Cp.DT? to calculate the temp rise of the cooling water?...I know all enthalpy figures at each state of the cycle - h1=3410 h2=2153 h3=192 h4=199 but am still having difficulty knowing what equations to use and what to put in? Thanks.
