Please just help with part D.
![a) A suction pump. Consider a pipe that is inserted vertically into
water. By suction, the pipe is evacuated of air. How high will the
water rise?
b) A water turbine is designed to extract kinetic energy from the hor-
izontal flow of water and convert it into rotation of the turbine. You
may assume that the height of the fluid does not change as it flows
through the turbine, and that the fluid is incompressible. If the velocity
is lowered from 100 m/s to 70 m/s as the fluid flows through the
turbine, what is the change in pressure?
c) Is the pressure higher upstream or downstream?
d) The fluid in (b) is replaced by air to make a wind turbine. What is
the change in pressure now for the identical change in velocity to (b)?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0724d636-1660-41e9-be6d-29c03d60387f%2Fa29bf6d1-b11e-4a35-83cc-6c9756b535c6%2Fvufwbf4_processed.png&w=3840&q=75)

Introduction:
We are given air flowing through turbine. We are given initial and final velocity of air. The density of air is
We are also given that height of air does not change. We apply Bernoulli theorem to find change in pressure.
