Question

While designing a hydraulic structure, the piezometric head at bottom of the floor is computed as 10m.The datum is 3m below floor bottom. The assured standing water depth above the floor is 2m. The specific gravity of the floor material is 2.5. The floor thickness should be

Answer 1

gravity of the floor material =2.5.

Floor thickness = 1.33×h/G−1

= 1.33×10−2−32.5−1 = 4.4.

so, The floor thickness should be 4.40m

Answer 2

Answer:

2m is true answer. rest is all wrong. i don't want to solve this question for you.
