Which of the following describes an engineer developing a possible solution to an engineering design problem A. Mr. Carmichael researches the amount angle, and duration of sunlight striking the area where an office building will be constructed B .Mr. Carmichael constructs a computer model of a proposed office building to evaluate its heating and cooling characteristics C. Mr. Carmichael proposes that facing a planned office building in a different direction might allow for a greater amount of passive heating D. Carmichael notices that the heating requirements for a proposed office building will be too great for the future tenants to afford

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.
