Answer 2

Step-by-step explanation:

Given In a pipe of 90 mm diameter water is flowing with a mean velocity of 2 m/s and at a gauge pressure 350 KN/m2. Determine the total head, if the pipe is 8 meters above the datum line. Neglect friction.

• So the total head is given by
•       total head = p/pg + v^2/2g + z which is a constant
• Diameter of the pipe = 90 mm
• Velocity of water v = 2 m/s
• Pressure p = 350 kN/m^2
• Datum head z = 8 m
• Specific weight of water w = 9.81 kN/m^3
• Now total head h = p/w + v^2 / 2g + z
•                             = 350 / 9.81 + 2^2 / 2 x 9.8 + 8
•                             = 350 / 9.81 + 4 / 19.6 + 8
•                             = 35.67 + 0.204 + 8
•                             = 43.88 m
