A pipe line 0.2m in diameter flowing full of water has a construction ...
To calculate the velocity in the construction and the discharge rate in cubic metres per second, we can use the following formulas:
Velocity in the construction:
Vc = (Vp * Dp) / Dc
Where Vc is the velocity in the construction, Vp is the velocity in the pipe, Dp is the diameter of the pipe, and Dc is the diameter of the construction.
Discharge rate in cubic metres per second:
Q = (π/4) * Dp^2 * Vp
Where Q is the discharge rate in cubic metres per second, π is the constant approximately equal to 3.14, Dp is the diameter of the pipe, and Vp is the velocity in the pipe.
Plugging in the given values, we get:
Velocity in the construction:
Vc = (2 * 0.2) / 0.1 = 4 m/s
Discharge rate in cubic metres per second:
Q = (π/4) * 0.2^2 * 2 = 0.0314 m^3/s
Therefore, the velocity in the construction is 4 m/s and the discharge rate in cubic metres per second is 0.0314 m^3/s.
