A liquid ( = 1.65 g/cm3) flows through two horizontal sections of tubing joined end to end. In the first section the crosssectional area is 10.0 cm2, the flow speed is 275 cm/s, and the pressure is 1.20 105 Pa. In the second section the crosssectional area is 3.50 cm2.
a.Calculate the smaller section's flow speed.
b.Calculate the smaller section's pressure.
I found part a but not b.
a. Use the equation of continuity A1V1=A2V2
b. Use bernoullis equation. If you post your work, perhaps we can help.
