To calculate the pressure head at point A, we need to consider the elevation head and the velocity head. The pressure head can be calculated using the following formula:
Pressure head (H) = Elevation head (h) + Velocity head (hv)
1. Elevation head (h):
The elevation head is the height of the point A above a reference point. In this case, the elevation is given as 30.5 m. So, the elevation head is 30.5 m.
2. Velocity head (hv):
The velocity head is the energy associated with the motion of the fluid. It can be calculated using the formula:
Velocity head (hv) = (v^2) / (2g)
where v is the velocity of the fluid and g is the acceleration due to gravity (10 m/s^2).
Given that the velocity of the water is 20 m/s, we can calculate the velocity head:
Velocity head (hv) = (20^2) / (2 * 10) = 20 m
3. Pressure head (H):
Now, we can calculate the pressure head by adding the elevation head and the velocity head:
Pressure head (H) = Elevation head (h) + Velocity head (hv)
= 30.5 m + 20 m
= 50.5 m
Therefore, the pressure head at point A is 50.5 m.
Answer: (d) 50.5m
Pressure head (H) = Elevation head (h) + Velocity head (hv)
1. Elevation head (h):
The elevation head is the height of the point A above a reference point. In this case, the elevation is given as 30.5 m. So, the elevation head is 30.5 m.
2. Velocity head (hv):
The velocity head is the energy associated with the motion of the fluid. It can be calculated using the formula:
Velocity head (hv) = (v^2) / (2g)
where v is the velocity of the fluid and g is the acceleration due to gravity (10 m/s^2).
Given that the velocity of the water is 20 m/s, we can calculate the velocity head:
Velocity head (hv) = (20^2) / (2 * 10) = 20 m
3. Pressure head (H):
Now, we can calculate the pressure head by adding the elevation head and the velocity head:
Pressure head (H) = Elevation head (h) + Velocity head (hv)
= 30.5 m + 20 m
= 50.5 m
Therefore, the pressure head at point A is 50.5 m.
Answer: (d) 50.5m
