Determine the weight of water in a pool with dimensions of 25 meters 4 meters 2 meters water density 1000 kg / m3.
| January 4, 2021 | education
Weight is indicated by P
(1) Р = mg, m – mass, g – free fall acceleration
(2) m = pV, V – volume, p – fluid density
Substitute (2) in (1)
P = pVg
Three measurements of the pool are given, that is, the volume
P = 1000 kg / m3 * 10 N / kg * 25 m * 4 m * 2 m = 2 000 000 N
Answer: P = 2,000,000 N
