Bob, do u know how to calculate the pressure drop in the sparger hole? I referred to Perry's, the formula is as below: delta P = 1/Co x Vo2/2 I get 5.9 psi. Is it realistic or not? What is the typical value for the pressure drop for a sparger system sparge air into the vessel?

yes, i did the calculation as u show to me. But the problem is the values of hi and ho are very high, hi=5024 W/m20C and ho = 3800 W/m20C. My design is actually an agitated reactor with immersed cooling coils. Cooling water is flowing inside the coils while glucose solution is outside the coil...

can i know whether the inside heat transfer coefficient, hi and the outside heat transfer coeffcient of water flows inthe pipe, ho is how much ? Is it must lie between the range of 1000 to 2000 W/m2.oC?

the sparger is used to help the agitation in the fermenter and also to increase the dissolved oxygen concentration. any deeper info pls let me know. From literature, the diameter of the orifice is around 6mm. It also stated that the total area of the holes is equal or less than the...

Thank u 4 ur help. i will try to solve this problem.

Hi, everybody. Recently i was assigned to do a plant design of monosodium glutamate plant. I need to know the mechanical design of a sparger, eg the diameter, the number of holes and the diameter of the hole. thanks for ur help.
