s the flow speed at location 2 higher or lower than at location 1?, General Physics II help

/in /by

1. A horizontal pipe carries a smoothly flowing liquid with density 1.29 × 103 kg/m3. At locations 1 and 2 along the pipe the diameters are 5.75 cm and 3.07 cm, respectively. Is the flow speed at location 2 higher or lower than at location 1?

A)The flow speed at location 1 is 2.25 m/s. What is the flow speed at location 2? (Notice that the two locations are at the same elevation).

B)What is the pressure difference between location 2 and location 1 (including its sign)? Ignore viscosity.

C)Is the pressure at location 2 higher or lower than at location 1?
