Question

Darcy- Weisbach equation gives relation between__________

(a) Pressure and temperature

(b) Mass, volume and pressure

(c) Head loss and pressure loss

(d) Pressure loss only

I got this question in my homework.

My query is from Loss of Head due to Friction in Viscous Flow in chapter Viscous Flow & Turbulent Flow of Fluid Mechanics

Answer 1

Right answer is (c) Head loss and pressure loss

Explanation: Darcy-Weisbach equation relates the head loss and pressure loss due to friction along a given pipe with a specified length. It contains a dimensionless friction factor called the Darcy friction factor. The equation was named after Henry Darcy and Julius Weisbach.
