Four kilograms of water initially at 200 degree Celsius and 0.5 MPa undergo an isothermal, internally reversible compression process to the saturated liquid state. Determine the work and heat transfer involved in the process (in kJ). Sketch the proce..
a car that weighs 3000 lb is traveling on a hill at a constant speed of 40.1 fps. the crest of the hill has a radius of
A 5cm-diameter horizontal jet of water with a velocity of 40m/s relative to the ground strikes a flat plate that is moving in the same direction as the jet at a velocity of 10m/s. The water splatters in all directions in the plane of the plate. How m..
