Water flowing through a 2.8 cm-diameter pipe can fill a 200 L bathtub in 5.8 min. Flow rate Q = volume/time = speed * cross section area Q=200/5.8=speed*.028....i get 1231.52 or Q=(200/348)=speed*.028...i get 20.52 both are wrong so what do i do? then i did speed=200/(pi*.25^2...

ok so i did speed=200/(pi*.25^2) ...i got 3.97 which is wrong maybe because i have to get the answer in m/s

weight= density*volume*g weight=700*(0.001)*9.81 weight=6.86newton weight=densitywater*g*10cm*10cm*depth 6.86=1000*9.81*.1*.1*d 6.86=98.1*d d=.0699...which is still wrong i have to get an answer in cm.

oh ok weight= density*volume*g weight=700*1000cm*9.81 weight=6867000 weight=densitywater*g*10cm*10cm*depth 6867000=700*9.81*10cm*10cm*d d=10 still didn't work,am i missing something?

weight= density*volume*g weight=700*10cm*9.81 weight=68670 weight=densitywater*g*10cm*10cm*depth 68670=700*9.81*10cm*10cm*d d=.1 it isnt right:-(
