How to estimate the size of a heat exchanger that is heat water up from 20C-120C.

5,000,000 g of H2O needed (5000 L H2O)

I have calculated that Q = 2.093*10^9 J

Please tell me how to determine what the size will be and how much power will be required for this heat exchanger to operate. please explain each step and equation

Expert Solution

so area required for heat exchanger is 44.77m2. And power required to operate heat exchanger is 2.093×10^9 Watt. All the calculations is done with the help of scientific calculator and some value is taken from heat transfer book.

Here we provided correct solution up to my knowledge.

Saturdated water vapor (steam) is commonly used as a heat source in heat exchanger applications. Why saturated vapor? Why saturated water vapor? In a plant of any reasonable size, several varieties of saturated steam are commonly available; for example, saturated steam at 4.5,9,17, and 33 bar. But the higher the pressure the lower the useful energy content (why?), and the greater the unit cost. Why then is higher-pressure steam used?

Determine the overall heat transfer coefficient (U) in a heat exchanger that uses steam to heat water to the point of vaporization (in vacuum.)

Determine the overall heat transfer coefficient (U) in a heat exchanger that uses steam to heat water to the point of vaporization (in vacuum.) The system is non-insulated, so the heat lost to the surroundings must be taken into consideration. While I know that the heat Q = mCdT and the heat transfer rate q = UAdT(Log-mean), I am struggling to equate the two due to the heat lost to the surroundings. How do I go about determining the overall...

Design a concentric tube heat exchanger (in co-current configuration) to heat 1000 cm3/ min of water from 30oC to 45oC flowing in the shell, using water at 65oC flowing in the tube. The heating water should not exit with temperature above 55oC. Choose a suitable range of inner pipe (copper material) diameters for heat exchanger, assume suitable inner tube thickness and outer tube diameter and show selection of parameters and dimensions for an optimum design.
