- Answer step by step. Subject: thermodynamics and Heat TransferQ2) The outer surfaces of the plane composite wall (A, B and C) are exposed to a fluid at 25'C and a convection heat transfer coefficient of 1000 W/m² "C. The thickness of walls A, B and C are 30, 60 and 20 mm, respectively. The thermal conductivity of walls material A, B and C are 25, 15 and 50 W/m "C, respectively. The middle wall (B) has a uniform heat generation, while there is no generation in walls A and C. The outer surfaces temperature of A and C are 132°C and 158°C, respectively. At steady state-one dimensional heat transfer conditions calculate: (1) The temperature in wall B at a distance of 10 mm from interphase of walls B and C. (2) The temperature in wall B at a distance of 5 mm from interphase of walls B and A. (3) The temperature at the middle of wall B.Question D is my main concern. This question is related to thermodynamics
- What happens to heat transfer per unit time in conduction heat transfer as thermal conductivity decreases?As the temperature increases, the thermal conductivity of a gas... (A) increases (B) decreases (C) remains constant (D) increases up to a certain temperature and then decrease2. A rectangular swimming pool is 1.5 m deep, 15 m wide, and 25 m long. Assume the bottom and sides of the swimming pool are insulated so that the pool exchanges heat with its environment through the top surface only. The density of water is 1000 kg/m³, the specific heat is 4180 J/kg-°C, and the heat transfer coefficient is 10 W/m²-°C. 1.5 m Heat exchange through top surface only 25 m T(t) To 15 m Complete the following. (a) Determine the thermal time constant of the pool and express your answer in days. (b) The swimming pool is being held at T0 = 30 °C when the power fails and external heating stops. The air temperature around the pool (T) drops quickly and can be assumed to be 10 °C at time t = 0. Write a script file in MATLAB® that plots the pool temperature for a duration of four thermal time constants.
