From one hospital, a small family rides their car and travels 25 km in a direction 30° south of west and then 30 km toward the north to a second hospital in search of a vacancy to accommodate a severe-case CoViD-19 relative patient. Where is the second hospital with respect to the first hospital, i.e. direction of the resultant displacement?

Assuming that there are no heat effects and frictional effects. find the kinetic energy and speed of a 3220 lb body after it falls 778 ft from rest.

State the limitations of Carnot cyle for a vapour power plant

A gas turbine receives gases from the combustion chamber at 7 bar and

650°C, with a velocity of 9 m/s. The gases leave the turbine at 1 bar with a

velocity of 45 m/s. Assuming that the expansion is Adiabatic and reversible

in the ideal gas,

calculate the power Output per unit mass flow rate,

1=1.333, Cp=1.11 KJ/Kg.K
