El agua fluye a 6m/s por un tubo de 6cm2 de área, pasa a otro de 3cm2 de área conectado al primero, cual es la velocidad en el tubo pequeño?

v2 = 12m/s

Explanation:

To find the velocity of water in the lower tube you use the following formula:

  (1)

v1: velocity in the first tube

v2: velocity in the second tube

A1: area of the first tube

A2: area of the second tube

From the expression (1) you can obtain the velocity v2, that is the velocity of water in the second tube:

you replace the values of the parameter in order to calculate v2:

hence, the velocity of the water is 12m/s

like poles repel so keep pushing north to north and repels funny to see this
