Hi,
I need to measure heat transfer coefficient in the block channel. However, the block is not general block. Inside block, there is trapezoid object. So, water flow rate in the first is low speed because big square.
Then the square size will decrease then the speed is high.
Do you know how to measure hydraulic diameter (Dh) of it?
