Hi all,

 

I am new to this forum and I hope I will clarify myself correctly and thanks for any kind of help

 

We are asked to design a jacketed vessel(vertically)  for a dairy plant with a capacity of 5 m^3 and available water temperature for inlet is 70 C and we assumed to drop to 60 C. The inside diameter of the vessel is 1.8 m and steel thickness is 0.005 m and jacket vessel is 0.02 m. We are still stuck in determining the flow rate of the water available to heat our milk mixture from 10 C to 43 C. How can we decide the flow rate of the water and the linear velocity?

 

Thanks again.

Determine the heat exchanged of the milk mixture that will be heated from 10 C to 43 C. Then from this heat exchanged calculation and the temperature rise of 10 c, calculate the amount of water required.

 

Assuming you have enough water pressure available, calculate a water flow that gives a Reynolds number of at least 2000 This will be conservative due to the curvature of the pipe. This assumes you are using a half pipe jacket.
