un tubo diametro interno variable transporta agua. En el punto 1 el diametro es de 20cm y la presion de 130kpa. En el punto 2 que esta 4.0m mas arriba que el punto 1 el diametro es de 30cm. si la tasa de flujo es de 0.080m3/s, cual es la presion en el segundo punto?

iron would move it is magnetic there is a mag field around the current in the wire

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
