The front door of an oven is made up of walls made up of materials A, B and C, juxtaposed. The walls that make up the door have thermal conductivities, kA= 20 W/(m.K), kB= 0.027 W/(m.K) and kC= 50 W/(m.K) and known thicknesses LA=0.30 m and LC=0.15 m. At steady state operation, measurements indicate that the air temperatures inside the oven and its inner walls are equal to 600 oC (the temperature of the inner surface of the door is not known). The convective coefficient of air (inside and outside the oven) is 25 W/(m2.K) and the radiation coefficient is hr=25 W/m2K. outside the air is at 25oC. Based on this information:(a) schematic the thermal circuit for the system;(b) estimate the minimum thickness of wall B to ensure that thetemperature of the outer surface of the door (exposed to ambient air)is ≤40oC in order to ensure the safety of operators;(c) estimate the temperature of the surface of the oven's inner wall Answer: (b) 40 mm; (c) 592.5oC
A current problem in the U.S. Air Force is the neck/shoulder fatigue experienced by pilots. To be able to fly missions at night, the pilots wear night vision goggles, which are attached to the front of the helmet. Unfortunately, these are heavy, causing a large downward torque of the head, which must be counteracted by the neck muscles, which then fatigue. To alleviate this problem, many pilots have started attaching random lead weights to the back of the helmet. Find the appropriate weight that would best balance the head and minimize neck fatigue – You must show your free body diagram. Assumptions: a) center of gravity of goggles is 20 cm in front of neck pivot point, b) load of goggles1.0 kg mass, c) center of gravity of lead weight is 10 cm behind neck pivot point, d) load of bare helmet 3 kg mass, e) center of gravity of helmet is 2 cm in front of neck pivot, f) load of head 4.0 kg mass, and g) center of gravity of head is right at neck pivot point.

1. The figure shows a pump that draws 840 L/min of crude oil (s= 0.85) in an underground storage drum to the first stage of a processing system; a) If the total energy loss in the system is 4.2 N m/N of oil flow, determine the power transmitted by the pump to the fluid. b) If the energy loss in the steel suction line is 1.4 N m/N of oil flow, determine the pressure at the pump inlet
An external wall of a building has a U value of 0.50 W/m^2K. The indoor temperature is21 degrees C and the outdoor temperature is -2.0 degrees C The steady-state heat loss is calculated to be 11.5W/m^2 The wall contains a layer of insulation 40 mm thick with a conductivity of0.035 W/mK. What would the insulation thickness need to be in order toreduce the steady state heat loss by 50%? answer = 0.11m please show all working

(C) The composite wall of a refrigerator consists of three different materials; A, B, and C. Two of the used materials have known thermal conductivity, ka = 30 W/m. K and kc=45 W/m. K, and known thickness, LA=0.20 m and Lc = 0.15 m. The third material, B, which is sandwiched between materials A and C, is of known thickness, LB = 0.15 m, but unknown thermal conductivity kB. Under steady-state operating conditions, measurements reveal an outer surface temperature of Ts,0 = 20°C, an inner surface temperature of Ts,i = 600°C, and a refrigerator air temperature of To∞ = 800°C. The inside convection coefficient h is known to be 25 W/m?.K. What is the value of thermal conductivity for material B?
