A weighted piston (total mass of 16.8 kg), resting on stops in a cylinder (radius of 0.05 m) divides a container into two regions. 0.075 kg of saturated liquid water at 50 °C is contained beneath the piston. The rest of the cylinder and container is evacuated. Heat is applied to the water until the piston is lifted off of the stops and moved a distance (y) of 0.6 m. As the piston reaches the mouth of the cylinder, the hermetic seal is broken and the cylinder contents can now expand to fill the remainder of the evacuated space.

1- A steam stripper is used to help removing wallpapers. It comprises of a tank of waterwith an electrical heating element. To generate steam, from which a long rubber tubeconveys the steam to the head which contact with the wallpaper to be removed.(i) The power rating of the electrical heating element is 2 KW, and the tank holds about3 liters of water. Estimate the time it would take from switching the power on tosteam to be generated. (ii) Once steam has started to be produced, estimate how long you could workcontinuously before having to refill the tank. Assume that all water initially in thetank can be evaporated into steam. Also, neglect any heat loss from the tank.Data :Room Temperature 20 oCHeat capacity of water, Cp 4.19 KJ kg-1 K-1Latent heat of vaporization of water at 100 oC, hfg 2257 KJ kg-1(iii) Stream is to be condensed in the condenser of a steam power plant at atemperature of 50 oC with cooling water from a nearby lake which enters the tubesof the condenser at 18 oC at…
