Asteam power plant operates on an ideal rankine cycle. superheated steam flows into the turbine at 3 mpa and 400oc with a flow rate of 100 kg/s and exits the condenser at 50oc as saturated water. determine (a) the net power output, (b) the thermal efficiency, and (c) the quality of steam at the turbine exit. (d) how would the efficiency change if the condenser temperature can be lowered to 30oc?

B? i feel like this is a trick  

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
