Hello, I want the preesure drop for Tee sections.I am using formula is ΔP=0.5*density*flow velocity ^2*resistance coefficient . In this formula i have to calculate the resistance coefficient .I tried in different ways but i didn't get formula. I have three different T sections. 1.Tee sharp edged 2.Branch flowing asunder 3.Branch flowing together I want resistance coeeficent formula for the above 3 cases. Please help me.Thanks in advance.
