What is the coefficient of friction between a serrated helical tube and a tube sheet support?
What is the coefficient of friction between a serrated helical tube and a tube sheet support?
(OP)
By tube sheet support, I mean the helical tube is supported by the tube sheet. The water is inside the tubes. Plus, how the coefficient of friction changes with increase in temperature? On engineering toolbox website for steel to steel it's 0.5 - 0.8 which sounds very high. Thanks.
