Air at 100 Fahrenheit and 2 atm is being passed over a shallow bed of naphthalene spheres that are 0.5 inch in diameter at a superficial velocity (v0) of 5 fts^-1. The MW of naphthalene is 128.2 g mol^-1, and it’s diffusivity in air at these operating conditions is 0.033 cm^2s^-1. The porosity of the bed is 0.40, and the total surface area of the naphthalene particles is 86.3 ft^2 for each 1 ft^3 of packed bed.The viscosity of air under these conditions is 0.0184 cP and the density of air is 0.0023 g cm^-3. The equilibrium concentration of naphthalene in the air under these conditions is 0.006 mol L^-1. Assuming the concentration of the naphthalene in the air stream is negligible, estimate the initial evaporation rate of the naphthalene in pounds per second from 1 ft^3 of bed.
An air at state point 1 (50°C dry bulb temperature and 25°C wet bulb temperature) experiences a temperature drop of 5°C as it passes through the 1.2-m wide stack of lumber. Determine the properties of the air at state point 2 with those at state point 1.

Calculate the time taken for a 7 um radius cloud droplet to grow via condensation into a 3500 um rain droplet. Assume a super-saturation of 1.55%, a water vapour density of 3 g m-3, and a water vapour diffusion coefficient in dry air of D=24 x10-6 m2 S -1 PLEASE SHOW CALCULATION
Thermal energy generated by the electrical resistance of a 5-mm-diameter and 4-m- long bare cable is dissipated to the surrounding air at 80°C. The voltage drop and the electric current across the cable in steady operation are measured to be 18 V and 5 A, respectively. Disregarding radiation, estimate the surface temperature of the cable. Evaluate air properties at a film temperature of 100°C and 1 atm pressure.
Hot water is being transported in a horizontal pipe (k = 0.15 W/m∙K, Di = 2.5 cm, Do = 4.5 cm), where the pipe inner surface temperature is at 100°C. A length of 2 m of the pipe outer surface is exposed to cool air at 12°C. Assuming that the properties of air can be evaluated at 40°C and 1 atm pressure, determine the outer surface temperature of the pipe. Is 40°C an appropriate film temperature for evaluation of the air properties?
A nuclear power station is situated in Coal Valley, which is a roughly rectangular valley that is 5 km long, 2 km wide, and 200 m deep. You have been asked to evaluate the effects of a worst-case scenario where the reactor housing fails, and radiation is released to the atmosphere. In your evaluation, you determine that 120 kg of Iodine-131 (a radioisotope that causes thyroid gland and liver damage) could be released into the atmosphere. Assuming the release of Iodine-131 was very rapid and all of it was uniformly distributed through the valley’s atmosphere with none escaping the valley, what would the concentration of Iodine-131 be in the valley’s air? Your answer should be expressed in units of ppm(v), and you may assume an atmospheric pressure of 1.0 atm and a temperature of 20oC. 2. Assuming the Iodine-131 concentration you calculated in part (a) is the initial concentration in the valley, you now want to determine the time it will take for the concentration to decrease to…

Consider a flat plate placed inside a wind tunnel, and air at 1 ATM and 20°C is flowing with a free flow velocity of 60 m/s. What is the minimum length of the plate needed for the Reynolds number to reach 2 × 107? If the critical Reynolds number for external flow is 5 × 105, what type of flow regime would the airflow experience at 0.2 m from the leading edge?
