Statement 2: Bents have more pressure drop than elbows.

(a) Union joint, True

(b) Union joint, False

(d) T- joint, False

I got this question in an online interview.

My doubt is from Unit Operations topic in chapter Food Processing Techniques, Fluid Mechanics and Rheology of Foods of Food Engineering

Answer 1

Correct option is (c) T- joint, True

To explain: When an additional connection such as a valve/ tap is to be added, T- joint is used.  Bents and elbows are both used when there is a change in the direction of flow. But, pressure drop in bents is more than in elbows, although bents are sturdier than elbows.
