Question

Total head is the sum of ________

(a) piezometric head and velocity head

(b) piezometric head and position head

(c) position head and velocity head

(d) velocity head and pressure head

I have been asked this question in final exam.

My question is from Seepage Analysis topic in division Seepage Analysis of Geotechnical Engineering I

Answer 1

Correct option is (b) piezometric head and position head

To explain: The total head is the sum of pressure head, velocity head and position head. The velocity head is considered negligible due to small flow of water. Therefore, total head is the sum of pressure head and position head.
