Water is subjected to various temperatures and pressures as indicated below draw a separate p-v and t-v diagram that includes lines of constant tand/or p for each set of temperatures and pressures label the p-v and t-v diagrams with values for each set of conditions below locate (approximately) the point(s) on the diagram that represents each t and p. draw the point(s) on each graph. identify the phase. a)-p=80 lb/in2, t=312.07°f b)-p=80 lb/in2, t=400 °f c)- t=400 f, p =360 lb/in2 d)-t= 320°f, p=70 lbt/in2 e)- t =10°f, p =14.7 lb/in2

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.

You are making beer. the first step is filling the glass carboy with the liquid wort. the internal diameter of the carboy is 15 in., and you wish to fill it up to a depth of 2 ft. if your wort is drawn from the kettle using a siphon process that flows at 3 gpm, how long will it take to fill?
