Governing Physics: 1. Conservation of Mass (Continuity Equation): $\dot{m} = \rho Q = \rho A V = \text{constant}$ 2. Euler's Turbomachine Equation (Energy Transfer): $H_{th} = \frac{u_2 V_{u2} - u_1 V_{u1}}{g}$ Where $u$ = tangential velocity, $V_u$ = tangential component of absolute velocity 3. Bernoulli's Equation (Energy Conservation): $\frac{P_1}{\rho g} + \frac{V_1^2}{2g} + z_1 + H_{pump} = \frac{P_2}{\rho g} + \frac{V_2^2}{2g} + z_2 + h_f$ Working Principle Sequence: 1. Fluid enters impeller eye at low pressure 2. Rotating impeller (2900 RPM) accelerates fluid radially outward 3. Centrifugal force increases fluid velocity (typically 10-30 m/s) 4. Volute casing decelerates fluid, converting velocity to pressure 5. Diffuser action in volute increases static pressure by 40-60%
