How to calculate time to empty a vertical cylindrical tank

This video describes simple formula to calculate time to empty a vessel

[gurudath]

Thank you for the video.... Please make the video to filling the empty tank...

Did you consider h is constantly 10 throughout the darining?!?

[ramesh.]

I have one doubt in this video:
What is 8?

[mahipaltechie]

How would you calculate the time to fill this tank based on the parameters: Diameter (D), Flow (F), and Height (H) ?

How to calculate our home overhead tank

[makmurmarzuki]

it is likely same with Time = 1/Cd x A/a x (2h/g)^2


Cd is Discharge Coefficient
A = Survace area of Vessel (1/4 x pi x D^2)
a = Survace area of Orifice (1/4 x pi x d^2)
h = heigh of water fluid surface to orifice oulet
g = gravity accelearation (9, 8 m/s2)

Sir how to calculate mmwc chart for lng tank

[vighnarajsarang]

Y coefficient of discharge is 0.82 it should be 0.62

D=3... Dia of tank

d=0.05 dia of orific
