Water is moving at a velocity of 2.17 m/s through a hose with an internal diameter of 1.60 cm. the fluid velocity in this hose’s nozzle is 14.5 m/s. what is the nozzle’s inside diameter, in cm?

0.619 cm

Explanation:

V = 2.17 m/s, diameter internal, D = 1.60 cm

v = 14.5 m/s, inside diameter, d = ?

According to the equation of continuity,

A V = a v

3.14 x (1.60/2)^2 x 2.17 = 3.14 x (d/2 )^2 x 14.5

5.5552 / 4 = d^2 x 3.625

d = 0.619 cm

this means that the temperature of both substances will be equal

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
