Arman is a Mechanical Engineer, and is hired to design a massive 400 MW power plant for the city of Dubai. Oren decides that the optimal efficiency would be obtained if the pressure of saturated vapor entering the turbine should be 12 MPa, and the pressure of saturated liquid exiting the condenser to be 0.007 MPa. Dubai is in the United Arab Emirates (UAE), where the water from the Persian Gulf is 40 °C and UAE environmental laws limit the exiting cooling water to a maximum temperature of 45 °C (in order to prevent damage to the local fishing industry). For Arman's power plant, calculate: a. heat input form the boiler (in MegaWatts) b. thermal efficiency с. mass flow rate of cooling water (in kg/s)

Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.
