of course liquid can flow through a pipe?
it would flow more easily through a narrow pipe
A device for controlling the flow of liquid can sometimes be a pipe.
Yes, easily.
That depends entirely on the viscosity of the liquid in the pipe ! Water would flow faster than oil !
For a fluid flowing in a pipe, the pressure loss will be greater for a liquid flow due to more frictional losses on the pipe walls.
Riser
The velocity of flow in any pipe is determined by three things. The internal pipe diameter, the mass flow rate of the liquid and the fluid density.
If you mean 24 INCH pipe, then yes, it will easily flow 8000 gallons per hour .
An externally operated valve regulating the flow of a liquid inside a pipe.
yes it would indeed!
The volume of flow will be the same, but the velocity will be increase through the 15ml pipe. Q=v*A.
