4. An object initially at an elevation of 5 m relative to Earth's surface with a velocity of 50 m/s is acted on by an applied force R and moves along a path. Its final elevation is 20 m and its velocity is 100 m/s. The acceleration of gravity is 9.81 m/s². Determine the work done on the object by the applied force, in kJ.

Q True or False 1. PMM1 states that: there can be no machine which would continuously supply mechanical work without some form of energy disappearing simultaneously. 2. The filling of a tank is an example of unsteady flow process. 3. For steam nozzle the change in potential energy is zero 4. In case of boiler the change in kinetic energy is zero. 5. For steady flow only interaction between system surroundings are work and heat. 6. Superheated steam behaves like a gas and therefore, it follows gas laws 7. Extensive properties do not depend on the mass of the system. 8. The change of internal energy for an isolated system is equal to heat and work. 9. With the use of centrifugal pump, the heat transfer is maximum. 10. For the flow in reciprocating compressor, the change in the kinetic energy is maximum

QUESTION 51 The following processes occurs in a reversible thermodynamic cycle: 1-2: Reversible polytropic compression at pressure 0.6 bar at volume 0.09 m to a pressure 11.1 bar and specific volume 0.3 m/kg. The index of compression may be taken as n. 2-3: Reversibly expansion with expansion index of 2 to pressure 1.6 bar. 3-1: Reversible cooling at constant volume to the initial state. Calculate the work for the compression in the process to 2 decimal places. Not in kilo or mega.
