Answer:
hydrostatic force is 327000.00 N
Explanation:
given data
base = 4 m
height = 5 m
density of water = 1000 kg/m3
to find out
hydrostatic force
solution
we know this is a triangle so we consider here a small strip PQ whoes area da in with length x and width dy
so area will be
da = base/H × height = base/H × y
so da = x dy = base/H × y dy
and we know pressure = ρ × g × h
here h = y
hydrostatic force = pressure × area
df = (ρ × g × h) × base/H × y dy
now integrate it from 0 to 5 height
f = ρ × g 
f = ρ × g 
f = ρ × g × 4/5 × 
now put value ρ = 1000 and g = 9.81
f = ρ × g × 4/5 × 
f = 1000 × 9.81 × 4/5 × (5³/3)
force = 7848 × 41.666667
force = 327000.00 N
hydrostatic force is 327000.00 N
'Gram', 'kilogram', and 'metric ton' are units of mass, not weight.
'Pound' can be either a unit of mass or of force. Most people
use it most of the time to mean weight.
Flase plant cells and animals cells have almost the same major parts but some parts are different or in different places
Only velocity uses direction of travel in its calculations.
