Q3. Oil of unknown properties is heated in a shell-and-tube heat exchanger with one shell pass and 20 tube passes. The oil flows through the shell, and hot water flows inside the single copper tube that has an inner diameter of 20 mm, a wall thickness of 2 mm, and a length of 3 m per pass. The water enters at 360 Kat a mass flow rate of 0.2 kg/s and leaves at...

An organic liquid is heated from 20°C to 40°C by hot water in a 1:1 pass shell-and- tube heat exchanger in counter-current flow. The inlet temperature of the water stream is 85oC and flows in the shell side. The organic liquid flows through a bundle of 200 tubes of outside diameter 21 mm with a wall thickness of 2 mm. The flows of the organic liquid and water are 40 kg s and 15 kg s1, respectively (a) Calculate the...

Can
you please answer the following question
0. (CLO6 - 4 Marks) A counter-flow double-pipe heat exchanger is to heat water from 20°C to 80°C at mass flow rate of 1.5 kg's. The heating is to be accomplished by hot oil available at 150C at a mass flow rate of 2.5 kg/s. The inner tube is thin-walled and has a diameter of 1.5 cm with the length of 60 m. Fluid property: Fluid Type Mass flow rate, The Specific heat,...

You need to use your metabolic rate in watts as calculate early( MR, or heat energy production and transfer). You are on holiday in a tropical paradise. On a typical day your rectal temperature is 37c and your mean skin temperature is 33c. Suddenly a malaria attack developed with a 7 day folds rise in MR, and you reach temperature plate of 40c with a mean skin temperature of 34c. The conductance if shell is measured if skin blood flows....

Problem 3 (20 points) A cross-flow heat exchanger consists of a bundle of 32 tubes in a long duct. Hot water at 150°C and a mean velocity of 0.5 m/s enters the tubes having inner and outer diameters of 10.2mm and 12.5mm and has to be cooled to 136°C. The tubes are made of steel of thermal conductivity k-40 W/m.K. Air at 10°c enters the exchanger (unfinned) with a volumetric flow rate of 1.0 m3/s. The convective heat transfer coefficient...
