Combustion gases from the exhaust of a boiler that come out at 300 °C and 1 atm, are usedto preheat to preheat water in an industrial facility by passing them through a benchof tubes, within which there is a mass flow of liquid water of 6 kg/s. TemperatureThe average wall surface of all pipes is 80°C. Gases enter the bank ofPerpendicular shaped tubes with a velocity of 4.5 m/s. The outer diameter of the tubes isof 2.1 cm, which are arranged in a manner aligned with longitudinal and transverse steps ofSL = ST = 8 cm. There are 16 columns in the direction of flow with eight tubes in each.Whereas exhaust gases have properties very similar to atmospheric air,Calculate the following:a) The average coefficient of heat transfer by convection, in [W/m2K]. (b) The amount of heat transferred per unit length of the tubes, in [W/m] c) The pressure drop through the tube bank, in [kPa]
During a visit to a plastic sheet factory, it is observed that a section of 45 mlength of a steam pipe, with a nominal diameter of 2 inches (6.03 cm in diameter)Outdoor plant) extends from one end of the plant to the other without any insulation. TheTemperature measurements at various points on the tube surface gave an average value170 °C, while the surrounding air temperature is 20 °C. The outer surfaceof the pipe is oxidized and its emissivity is 0.7 on average with a temperature of thearound 22 °C. Calculate the following:(a) The coefficient of convective heat transfer for the air surrounding the pipe.b) The amount of heat lost by convection and radiationc) The amount of energy that is lost in a full day, assuming conditions ofconstant temperature.

Consider a polymeric membrane within a 6 cm diameter stirred ultrafiltration cell. The membrane is 30 μm thick. The membrane has pores equivalent in size to a spherical molecule with a molecular weight of 100,000, a porosity of 80%, and a tortuosity of 2.5. On the feed side of the membrane, we have a solution containing a protein at a concentration of 8 g L-1 with these properties: a = 3 nm and DAB = 6.0 × 10-7 cm² s¹. The solution viscosity is 1 cP. The hydrodynamic pressure on the protein side of the membrane is 20 pounds per square inch (psi) higher than on the filtrate side of the membrane. Assume that the hydrodynamic pressure difference is much larger than the osmotic pressure difference (advection >> diffusion). Determine the convective flow rate of the solution across the membrane.arrow_forward1. Calculate the filtration flow rate (cm³ s¹) of a pure fluid across a 100 cm² membrane.

The pores run straight through the membrane and these pores have a radius of 0.225 μm. The pressure drop applied across the membrane is 75 psi. (Note: 1 cP = 0.001 N s m²² = 0.001 Pa s.)arrow_forward
