In the following problem, consider the human body as a heat engine with efficiency e = 0.2 that can take in energy as food Qh, perform work W, and generate heat Qc. This heat expelled from our muscles (Qc) is an important component of maintaining a constant body temperature, which necessitates a balance of energy intake and output. In order to calculate the energy intake Qh, you will use the table above listing activity factors for selected activities, for a person with a BMR of 1440 kcal/day. For example, the energy required to stand per hour would be (fstand)(BMR) = (1.7)(1440 kcal/day) (1day/24 hours) = 102 kcal/h. For each scenario, calculate the 24 h number of bowls of cereal that must be consumed per hour (1 bowl = 100 kcal) to perform the required activity (Qh) Determine whether you have an energy deficit or surplus by considering the heat generated by your muscles (Qc), the heat loss from conduction, and the heat loss/gain from radiation We will consider heat loss from…
Choose the CORRECT relation between the Coefficient of Performance (CoP) for Refrigerator and Heat Pump? Select one: (CoP)Refrigerator = (CoP)Heat Pump + 1 o (CoP)Heat Pump = (CoP)Refrigerator + 1 o (CoP)Refrigerator + (CoP)Heat Pump o (CoP)Refrigerator = (CoP)Heat Pump 1 o (CoP) Refrigerator – (CoP) Heat Pump Clear my choice
A refrigerator (COP = 2.5) is used to maintain a lab temperature at 18° C for that 80 MJ of heat is absorbed. Then its work input would be 8.889 kJ/s. Select one: O True O False
3- Three refrigerators in Figure 4, shown with the designations A, B, and C are working in a temperature range of TH=32 °C and T1=3 °C. Among these three refrigerators, while the first refrigerator (A) is known to be a reversible, on the other hand, the other two (B and C) are known to be an irreversible and an impossible type, respectively. So, a) Calculate the COPR value of the refrigerator A under these temperature limits. b) Based on your Carnot calculations, give a COPR value for B which can be accepted as an irreversible refrigerator. And discuss why the value that you had chosen can be chosen as an irreversible refrigerator COP value. c) Again, based on your Carnot calculations, give a COPR value for C which can be accepted as an impossible refrigerator. And discuss why the value that you had chosen can be chosen as an impossible refrigerator COP value.
