Question

Water flows through a horizontal pipe whose internal diameter is 2 cm

Answer 1

hi there friend !!!!!!!!!!

Assuming that you have enough pressure to maintain the velocity of 1m/s in the pipe, then the velocity is dependent on the area of the aperture (nozzle). So, you want a nozzle with an area ¼ of the pipe area.

Since A = πr^2, the radius of the nozzle must be half the radius of the pipe.

So, the diameter of the nozzle is ½(2cm) = 1cm.
