Water (cp=4179 J/kg·K) at 30 °C flows on the inside of a steel tube with 25 mm inner diameter and 0.4 mm wall thickness at a flow rate of 0.4 kg/s. The tubes forms inside of a counter flow double pipe heat exchanger. Engine oil at 100 °C flows in the annular space with a flowrate of 0.1 kg/s. The outlet temperature of the oil is 60 °C. The material of the heat exchanger is carbon steel with k=45 W/m·K. The inner diameter of the outer tube is 55 mm. If the length of a hairpin is 5m, calculate the number of hairpins ignoring the fouling resistances.

please can you help me course name heat exchangers.

A stainless steel ball (? = 8055 kg/m3 , CP = 480 J/Kg? K ) of diameter D = 15cm is removed from the oven at a uniform temperature of 350 Degrees C. The ball is then subjected to the flow of air at 1 atm pressure and 30 degrees C with a velocity of 6m/s. The surface temperature of the ball eventually drops to 250 degrees 250 degrees C. Determine the average convection heat transfer coefficient during this cooling...

A fire-tube boiler made from carbon steel in which fuel gas flows within the tube while the boiler feed-water along with condensate from the plant flows on the shell-side. Visual inspection revealed heavily localized tubercles were seen on the outside surface of several tubes. After about 11 months of operation, the pipe was leaked and visual inspection found pin holes outside surface contain loose brownish rust. The rust contained chloride and was acidic in nature. Select appropriate corrosion prevention to...

1. Engine oil (cp = 2100 J/kg-°C) is to be heated from 20 °C to 60 °C at a rate of 0.3 kg/s in a 2-cmdiameter thin-walled copper tube by condensing steam outside at a temperature of 130 °C (hfg = 2174 kJ/kg). a. For an overall heat transfer coefficient of 650 W/m2 -°C, determine the rate of heat transfer and the length of tube required to achieve it. Determine also the rate of steam condensation, in kgsteam/sec. (Ans: 25.2...

A shell-and-tube heat exchanger is to used to heat water (in the tube side) from 30 deg C to 40 deg C at a mass flow rate of 4 kg/s. The fluid used for heating (shell side) is water entering at 90 deg C with a mass flow rate of 2 kg/s. A 1-2 STHE is used and the overall heat transfer coefficient based on the inside area is 1390 W/m2-K. The tubes are 1.875 in diameter (inside) and require...

A shell-and-tube heat exchanger heats oil from 2°C to 35°C using hot water. The oil flows in the shell in a single pass. Water flows in 5 copper tubes with a total (all tubes) rate of 0.5 kg/s. Each tube makes 4 passes through the shell and the length per pass is 4 m. The tube inner and outer diameters are 15 mm and 19 mm. The water enters at 95°C and leaves at 29°C. 1. Estimate the average convection...

1. Explain why a packed fractionating column (steel wool inside the glass tube) is more efficient than an unpacked one for distillation? Explain in detail. 2. If 3 spots on a TLC, plates have the following Rfs, A= 0.43, B=0.89, and C=0.53 what would be the order that the spots came off a column? What would happen if you increased the polarity of the solvent?
