points 1 and 2 lie on a streamline, the fluid has constant density, the flow is steady, and there is no friction. Although these restrictions sound severe, the Bernoulli equation is very ... found ...

So the total angle that we’d put in the capstan equation is given by θ 1 + θ 2. What’s key here is that only two properties, bend angle and coefficient of static friction, will dictate just ...
