02/! A Venturi meter is to be fitted to a * 12.5 cm radius pipe, in which the maximum velocity is 2.44 m/s and the pressure head is 6 m of water. What is the maximum diameter of throat, so that there is non-negative head on it. cd=1 .1, Add file 03// The Power (P) required to drive the * pump depends upon the diameter (D), the angular velocity (0.)), the discharge (0), and the fluid density (p). Drive expression for (P) by l'ltheorem method
