A liquid with a density of 1.65 g/cm3 flows from left to right in the pipe, from larger to smaller cross section. The left side's cross-sectional area is 10.0 cm2, and while in this side, the speed of the liquid is 2.62 m/s, and the pressure is 1.20 ✕ 105 Pa. The right side's cross sectional-area is 3.00 cm2. What is the velocity and and pressure?

Expert Answer

Step 1

The density of the liquid is 1650kg/m3. Let the area of cross section of the left end be 10.0cm2, speed of the liquid is 2.91m/s, and pressure be 1.20Pa. The area of cross section at the right end be 4.50cm2.

Step 2

(a)Write the equation ...
