c
Explanation:
it's the only engineering career
Answer:

Explanation:
The phenomenon can be modelled after the Bernoulli's Principle, in which the sum of heads related to pressure and kinetic energy on ground level is equal to the head related to gravity.

The velocity of water delivered by the fire hose is:


The maximum height is cleared in the Bernoulli's equation:



Answer:
The minimum diameter is 1.344 in
Explanation:
The angular speed of the driveshaft is equal to:

Where
N = rotational speed of the driveshaft = 2900 rpm

The torque in the driveshaft is equal to:

Where
P = power transmitted by the driveshaft = 134 hp = 73700 lb*ft/s

The minimum diameter is equal to:

Where
T = shear stress = 6100 psi
τ = 242.68 lb*ft = 2912.16 lb*in
