Question

A pipe with an internal diameter of 2.64 cm attaches to a hose with an internal diameter of 1.242 cm. It is determined that water flows through the pipe with a velocity of 0.812 m/s. With what velocity does the water flow through the hose?

Answer 1

(1) Internal diameter of pipe, D = 2.64 cm;

velocity of water in the pipe V = 0.812 m/s = 81.2 cm/s

Internal diameter of hose, d = 1.242 cm;

let the velocity of water in the hose is v.

Apply continuity equation;

velocity of water through the hose;
