An ideal rankine cycle has saturated water vapor 1.5 mpa leaving the boiler. the turbine exhausts to the condenser operating at 80 kpa. find the specific work and heat transferred in each of the ideal cycle components and compute the efficiency of the cycle. compare your rankine cycle efficiency to the carnot cycle efficiency operating between the same temperatures.

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Agas mixture consists of 8 kmol of h2 and 2 kmol of n2. determine the mass of each gas and the apparent gas constant of the mixture.

Steel balls 12 mm in diameter are annealed by heating to 1150 k and then slowly cooled to 400 k in an air att 325 k and h -20 w/m2 k. assume the properties of the steel to be k- 40 w/m k,p 7800 kg/m3, and cp 600 j/kg k. a. determine whether lumped system method can be used to analyze this problem and if so why" b. determine the time required for the cooling process. c. determine the total amount of heat lost from each ball to the ambient air
