A thin liquid film of ammonia (NH3), which has formed on the inner surface of a tube of diame D= 10 mm and length L = 1 m, is removed by passing dry air through the tube at a flow rate m = 3 x 104 kg/s. The tube and the air are at 25°C. a) Calculate the velocity, the Reynolds number Rep and Sherwood's number Sc. b) What is the average mass transfer coefficient hm? (Hint: Use Table 14-13)
3. Dye for our new line of blue jeans is being blended in a mixing tank. The desired color of blue is produced using a concentration of 1500 ppm blue dye, with a minimum acceptable concentration of 1400 ppm. At 9 A.M. today the dye injector plugged, and the dye flow was interrupted for 10 min, until we realized the problem and unclogged the nozzle. For how many minutes was the flow leaving the mixer off-specification (< 1400 ppm)? How many gallons of off-spec dye were made? See Fig. P5-15.

Q/ Air is to be bubbled through the solution in the reactor CSTR, in order to strip out of the solution trace amounts of a solvent that have contaminated the water. The rate of loss of the solvent from the solution can be characterized by the equation r = -0.03/min c, where c is the solvent concentration. What fraction of the solvent will be removed from the water as it passes through the reactor with residence time is 26.4 min.
An 80m deep and 100m wide river flows from the left to the right off the page. An action will release two sources of oil to the river: (1) the indirect runoff of oil accumulated on a bridge that runs off site and crosses over the river and (2) the direct and permitted discharge of water containing oil from the activities onsite (a water pollution control plant) to the river. The oil has a molecular weight of 100 g/mol, it fully dissolves in the river water, and it decays in the river with a rate constant of 0.2 d-1. Estimate the potential impact of this action on the concentration of oil in the river at a location 500m downstream of the WPCP. (1) bridge runoff Q1 = 1 m's C = 1 mol/m (2) WPCP discharge Q2 = 50 m's C2 = 0.01 mol/m Qin = 1000 m³'s Cin = 0.001 mol/m? --500m- 500m- -500m 80m 100m a.

Design a hydrocooling unit to cool down fruits and vegetables from 30 °C to 5 °C in 20 minutes at a rate of 20,000 kg of fruit or vegetables/h. The design must fulfill the following requirements: The unit will be an immersion flooded system. It must be able to cool down and transport the products in chill water. The tank has the following dimensions approximate. three meters wide and up to 90 cm hight. The water will circulate and be cooled through the evaporation section of a refrigeration system. The refrigerant temperature inside the coils will be -2 °C, and the water temperature must not drop below 1 °C and must not exceed 6 °C. Assuming reasonable values for the average density, specific heat, and porosity of the product (the fraction of the volume of air in a box), recommend reasonable values for: The speed of the water through the canal, the capacity of the cooling system. the compressor power.

With the pipe system in the figure, the water taken from a very large reservoir is poured into the atmosphere. Pipe diameters are 0.3 m in wide parts and 0.25 m in narrow parts. Assuming ideal flow and absolute evaporation pressure of 0.02 kg/cm2; a-) When X=2.5 m, determine the flow rate of the system and the velocities in sections 2 and 4. b-) Calculate the pressures in parts 1,2 and 3. c-) Calculate the maximum value that X elevation can take without changing the flow of the system.
ANSWER this, please.With the formula derived and the conditions applied in problem statement # 1, calculate for the heavier liquidoverflow leg, the diameter, and the volume of the tank in separating liquid B from liquid A having densities of 1278kg/m3 and 794 kg/m3, respectively. The volumetric flow rate of the mixture entering the tank is 30 m3/hr and the viscosity of the lighter liquid (continuous phase) is the same as the viscosity of water @ 35oC. Volume of heavier liquid is twice the volume of the lighter liquid and having a tank diameter to height as 1:2 ratio. Assume for 10% from the tank volume allotted for the vapor space having a pressure of 50 kPa. REFERENCE: (problem 1) Derive a formula to calculate for the height, ZC of the heavier liquid overflow leg in a continuous vertical cylindrical decanter.

As a process engineer, you are designing a new drinking water treatment plant using conventional treatment process including Two Trains of Flocculators as follows: The design flow is 0.35 m³/s. The average temperature of water is 5°C with a dynamic viscosity, μ = 1.519 x 10-3 Pa.S and p = 999.967 kg/m³. The major target of the WTP is to remove color from water using alum as coagulant. GAvg 0 = 120,000. In each train of flocculators, it includes three same size compartments in series with the tappered velocity gradients G: 80, 50, and 20 Sec-¹. Length = Width = Depth for each Comparment. The type of impeller is axial-flow with three blades. The available impeller diameters are 1.0, 1.8 and 2.7 m. The water depth below the impeller, B = 1/3 H. H is the water depth in flocculator.
