a cylinder contain 10kg of a certain fluid at an initial pressure of 40bar the fluid is allowed to expand reversible behind a piston according to a law pv^2= constant until the volume is doubled. the fluid is then cooled reversibly at constant pressure until the piston regains it original position heat is then supplied reversible with the piston firmly locked in position until the pressure rises to the original value at 40bar. calculate the network done by the fluid for an initial volume of 0.05m^3​

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.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux
