Here's wat I did:
I changed evrything to meters and i Knew that the density of water was 1000 kg/m^3
129000 Pa + (.5 * 1000kg/m^3 * (.274m/s)^2)=
(second Pressure) + (.5 * 1000 *(2nd Velocity)^2)
So...
(133054.104 - (second Pressure))/540 = (Second Velocity)^2
Here is a problem don't understand:
A liquid with a density of 1.08*10^3 kg/m^3 flows through two horizontal sections of tubing joined to the end. In the first section the cross sectional areais 10.5 cm^2, the flow speed is 274 cm/s, and the pressure is 1.29*10^5 Pa. In the second section, the...
