ammonia refrigerant is attached. 5. The wall of a cylindrical evaporating pan 1.8 m high and 1.2 m in diameter has an outer surface temperature of 82 °C. The temperature of the surrounding air is 16 °C. Calculate the total heat loss from the wall surface. Use the following data: Emissivity of the surface = 0.9, Stefan-Boltzmann Constant = $5.67 * 10^{-8}$ W/m$^2$ K$^4$, Coefficient for cubical expansion of air = 0.0031 °C, Viscosity of air = $1.65 * 10^{-5}$ kg/ms, Thermal conductivity of air = 0.026 W/m °C, Density of air = 1.122 kg/m$^3$, Average specific heat of air = $1.05 * 10^3$ J/kg °C, For natural convection the Nusselt equation is given by: Nu = c (Gr.Pr)$^n$ Where for turbulent flow: n = 0.33 and c = 0.12, for natural flow: n = 0.25 and c = 0.56. The characteristic dimension is taken as the height of the cylinder.

2. A tank containing 100 gallons of water initially has 10lbs of salt dissolved in it. A solution containing 0.55 lbs of salt per gallon is pumped into the tank at a rate of 2 gallons per minute. The solution is then mixed thoroughly and is removed from the tank at the same rate of 2 gallons per minute. a. (4 pts) Set up a differential equation and solve for Q(t) the amount of salt in the tank at time t. Recall that $\frac{dQ}{dt}$ = amount in \textendash{} amount out. b. (1 pts) What is $\lim_{t \to \infty} Q(t)$?

a) The outlet temperature of the water is not provided in the text. b) The overall heat transfer coefficient based on the outer surface of the inner tube can be calculated using the formula: 1/U = 1/hi + (do * ln(do/di))/(2 * π * k) + (do * ln(do/di))/(2 * π * k) where: U = overall heat transfer coefficient hi = heat transfer coefficient on the inner surface of the inner tube do = outer diameter of the inner tube di = inner diameter of the inner tube k = thermal conductivity of the inner pipe material c) The required pipe length can be calculated using the formula: L = Q / (U * A * ΔTlm) where: L = required pipe length Q = heat transfer rate U = overall heat transfer coefficient A = surface area for heat transfer ΔTlm = log mean temperature difference
