Expert Solution
Step 1 Bernoullis Equation

Bernoulli equation is based on law of conservation of mecanical energy .

It is applicaple for steady and unfiorm flow.

Summation of pressure head , velocity head and datum head remain constant . If we consider zero head loss. 

Bernoulli equation applicable along the stream line.

At point A :

Pressure head P1 = 22.1ft 

Velocity head calculated using Discharge and Area V1 

Area = 0.785 (d1)2

Datum head z1 = 10 ft

At point B 

Pressure head P2 

Velocity head calculated using Discharge and Area V2

Area = 0.785 (d2)2

Datum head z2 = 10 ft
