The net work output and the thermal efficiency for the carnot and the simple ideal rankine cycles with steam as the working fluid are to be calculated and compared. steam enters the turbine in both cases at 5 mpa as a saturated vapor and the condenser pressure is 50 kpa. in the rankine cycle, the condenser exit state is saturated liquid and in the carnot cycle, the boiler inlet state is saturated liquid. draw the t-s diagrams for both cycles.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.

An engine, weighing 3000 n, is supported on a pedestal mount. it has been observed that the engine induces vibration into the surrounding area through its pedestal at the maximum operating speed. determine the stiffness of the dynamic vibration absorber spring in (n/m) that will reduce the vibration when mounted on the pedestal. the magnitude of the exciting force is 250 n, and the amplitude of motion of the auxiliary mass is to be limited to 2 mm note: in this question type-in right numbers, no decimals, no fractions, no unit. approximate to right number if needed
