A 1/60 scale model is to be used in a towing tank to study the water motion near the bottom of a shallow channel as a large barge passes over (see the Video). Assume that the model is operated in accordance with the Froude number criteria for dynamic similitude. The prototype barge moves at a typical speed of 10 knots. (a) At what speed (in ft/s) should the model be towed

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
