Dear Leon666, Thanks for the answer. I need to find the volumetric flow rate (m^3/s),Q of the gas bubble come out from the triangular teeth. Total area,A for the teeth is 0.0016m^2, velocity,v = unknown (m/s). I wonder is there any formula can be used to calculate the velocity of the bubble, so...

Homework Statement Imagine that you are blowing air through a straw in a cup of water and the root of the straw was connected through a rectangular box with empty base and every side of the rectangular box was cut into "teeth" shape. Bubbles will come out from the teeth of the rectangular box...

Hi Berkeman, I'm working on biogas project, where we are using bacteria to generate the gas and turn it into electricity. The cooling pond functioned to cool down the temperature of the incoming POME (waste) which come from the palm oil mill factory after the extraction of the palm oil. This...

Thank you for the sharing of idea. It is a good idea of adding sprinkler/mist as it does not involved additional electrical consumption. How about the further modification of heat transfer calculation from the data sheet? Kindly advice.

Dear Bystander, Enclosed with the excel calculation sheet that i had done previously. Notice that, the formula used was for conduction and evaporation, where Bowen's conduction-evaporation coefficient was applied. However, no heat load applied in the calculation. For apply of convection only...

Hi Bystander, thank you for the reply. Convection, q = hA(T0 - T1). What about the density of the POME? Do you have any idea on it? I

Dear All, Referring to the subject above, I have found the calculation of heat load based on [Lawrence,K.W., Norman, C. P. & Yung, T. H. (2005). Advanced Air and Noise Pollution Control. Totowa: Humana Press.] My cooling pond system: 1. Purpose: cooling POME temperature from 70 to 40 degree C...

I'm a design engineer for biogas plant. I wish to share and get some advice from the experts at here. Wish everyone a very good day :smile:
