Revisit Example 6 from your Module 4 notes. Consider the well-insulated, rigid tank having a volume of 10 [ft']. Previously, it contained saturated water vapor at 212°F at state 1. The water was rapidly stirred until the pressure was 20 [Ibfin'j. In class we showed that the temperature at state 2 was 445°F and the work done during this process was -31.3 [Btu]. Now, if insulation were removed from the tank, and the water is cooled at constant volume from T: = 445°F to T3= 300°F without stirring the water, determine: a) The pressure at the state 3 in (Ibfin), and b) The heat transfer during the process in [Btu].

An exterior wall of a house may be approximated by a 4-in layer of common brick [k =0.7 W/m · ◦C] followed by a 1.5-in layer of gypsum plaster [k = 0.48 W/m · ◦C]. What thickness of loosely packed rock-wool insulation [k = 0.065 W/m · ◦C] should be added to reduce the heat loss (or gain) through the wall by 80 percent?

D-Q-1 Write T for true Statement or F for False Statement. [1]. Heat transfer: is transit mass between the bodies of materials due to the temperature difference [2]. Conduction: is this phenomenon replay to random motion, translational motion, rotational motion and internal vibrational motion of particles. [3]. The thermal diffusivity represents how fast heat diffuses through a material [4]. A material that has a low thermal conductivity or a low heat capacity will have a large thermal diffusivity. [5]. Heat transfer by radiation does not require the presence of an intervening medium. Convection is the mode of energy transfer between a solid surface and the adjacent liquid or gas that is in motion [6]. [7]. Conduction: is cold transfer from the higher particles activity to lower activity due to the temperature difference [8]. The larger the thermal diffusivity, the non-faster the propagation of heat into the medium [9]. The convection heat transfer coefficient in W/m. [10]. he rate of…
