Question

Fluid Mechanics Problem:

Assume, sand flow is a continuum.

Assume, sand build up is negligible.

to = nothing has moved yet.

W = Wo = weight of sand in hourglass

to < t < t1 , t1 = time at which the first grain of sand hits bottom.

t1 < t< t2 , t2 = time at which the last grain of sand leave the top.

T2 < t < t3 , t3 = time at which the last grain of sand hits the bottom.

t > t3 , W=Wo

Plot qualitatively indicated weight vs. time. Use matlab, excel, or any method for plot.

this is an inelastic case....where time period increases consistenly :)

thts a hint fr u :)

solve it once

if u need further help mail me pulkitagrawa@gmail.com
