Afour-cylinder, two-stroke 2.4-l diesel engine that operates on an ideal diesel cycle has a compression ratio of 22 and a cutoff ratio of 1.8. air is at 70°c and 97 kpa at the beginning of the compression process. using the cold-air-standard assumptions, determine how much power the engine will deliver at 3500 rpm. the properties of air at room temperature are cp=1.005 kj/kg-k, cv=0.718 kj/kg-k, r = 0.287 kj/kg-k, and k = 1.4. the power the engine will deliver is kw? ?

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
