- figure is the aschematic drawing of asolid counter Shaft that supports two flat belt zulless each having ason weight. For each puller, the best rensions are parallel and the coessicient de friction between the belt and Pelley Ais oils. If a cold-drawn wNs G10180 steel shast of wintorn diameter many w material properties of allowable strength in shear and intenders be taken as 220 MPa 440 MPa respectively. Determine the minimum Preferred size diameter in accordance to the ASME code usino km= 15 and Kt=1.0. Neglect the effect of mass and thickness of belts and mass of the shaft,

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.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned
