Aplanenozzle discharges vertically downward to

atmosphere. the nozzle issupplied with a steady flow of water. a

stationary, inclined, flatplate, located beneath the nozzle, is

struck by the water stream. the stream divides and flows along the

inclined flat plate; the twostreams leaving the plate are of

unequal thickness. frictional effects arenegligible in the

nozzle and in the flow along the plate surface. evaluate the minimum

gage pressure required at the nozzle inlet. calculate the magnitude

and direction of the force exerted by thewater stream on the

inclined plate. sketch the pressuredistribution along the surface

of the plate. explain why thepressure distribution is shaped the

way you sketched it.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
