Question

A liquid of density 1.17 × 103 kg/m3 flows steadily through a pipe of varying diameter and height. At location 1 along the pipe the flow speed is 9.47 m/s and the pipe diameter is 1.11 × 101 cm. At location 2 the pipe diameter is 1.77 × 101 cm. At location 1 the pipe is 9.45 m higher than it is at location 2. Ignoring viscosity, calculate the difference between the fluid pressure at location 2 and the fluid pressure at location 1.
