Given a rankine cycle with reheat operating with the following conditions: boiler exit conditions: 10 mpa, 600°c, and 7 kg/s: reheat exit conditions: 1.6 mpa and 600°c; condenser operating pressure: 30 kpa. you may assume all devices are ideal. determine the power output, heat transfer rate input required, and thermal efficiency of the plant.

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.

Shafts are machine elements that are used to a) carry axial loads b) direct shear loads c) transmit power d) rotate at constant speed e) none of the above circular and square shafts subjected to the same torque under the same circum behave a) the same way b) almost the same way

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
