Rankine's Efficiency of Hydraulic Ram

Formula

η r = \frac{q \cdot (H - h)}{h \cdot (Q - q)}

Example

0.583333 = \frac{0.0022 m³/s \cdot (21.5 m - 3.3 m)}{3.3 m \cdot (0.023 m³/s - 0.0022 m³/s)}

Rankine's Efficiency of Hydraulic Ram Solution

STEP 0: Pre-Calculation Summary

Formula Used

Rankine's Efficiency = (Discharge from Valve Box*(Height of Water in Delivery Tank-Height of Water in Supply tank))/(Height of Water in Supply tank*(Discharge from Supply Tank-Discharge from Valve Box))
η_r = (q*(H-h))/(h*(Q-q))
This formula uses 5 Variables

Variables Used

Rankine's Efficiency - Rankine's efficiency of hydraulic ram is the efficiency of the hydraulic ram calculated considering a Rankine cycle of flow.
Discharge from Valve Box - (Measured in Cubic Meter per Second) - Discharge from valve box is the volume flow rate of the water from the valve box to the delivery tank of an hydraulic ram.
Height of Water in Delivery Tank - (Measured in Meter) - Height of water in delivery tank is the water level available in the delivery tank of an hydraulic ram.
Height of Water in Supply tank - (Measured in Meter) - Height of water in supply tank is the water level available in the supply tank of an hydraulic ram.
Discharge from Supply Tank - (Measured in Cubic Meter per Second) - Discharge from supply tank is the volume flow rate of the water from the valve box to the valve box of an hydraulic ram.

STEP 1: Convert Input(s) to Base Unit

Discharge from Valve Box: 0.0022 Cubic Meter per Second --> 0.0022 Cubic Meter per Second No Conversion Required
Height of Water in Delivery Tank: 21.5 Meter --> 21.5 Meter No Conversion Required
Height of Water in Supply tank: 3.3 Meter --> 3.3 Meter No Conversion Required
Discharge from Supply Tank: 0.023 Cubic Meter per Second --> 0.023 Cubic Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

η_r = (q*(H-h))/(h*(Q-q)) --> (0.0022*(21.5-3.3))/(3.3*(0.023-0.0022))

Evaluating ... ...

η_r = 0.583333333333333

STEP 3: Convert Result to Output's Unit

0.583333333333333 --> No Conversion Required

FINAL ANSWER

0.583333333333333 ≈ 0.583333 <-- Rankine's Efficiency
