Efficiency of Transmission Solution

STEP 0: Pre-Calculation Summary

Formula Used

Efficiency = (Total Head at Entrance-Head Loss)/Total Head at Entrance
η = (H_ent-h_f)/H_ent
This formula uses 3 Variables

Variables Used

Efficiency - The Efficiency of an electric motor is defined as the ratio of usable shaft power to electric input power.
Total Head at Entrance - (Measured in Meter) - Total Head at Entrance is the measure of fluid's potential at the entrance.
Head Loss - (Measured in Meter) - Head Loss is a measure of the reduction in the total head (sum of elevation head, velocity head and pressure head) of the fluid as it moves through a fluid system.

STEP 1: Convert Input(s) to Base Unit

Total Head at Entrance: 1.6 Meter --> 1.6 Meter No Conversion Required
Head Loss: 1.2 Meter --> 1.2 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

η = (H_ent-h_f)/H_ent --> (1.6-1.2)/1.6

Evaluating ... ...

η = 0.25

STEP 3: Convert Result to Output's Unit

0.25 --> No Conversion Required

FINAL ANSWER

0.25 <-- Efficiency

Define efficiency?

The ratio of the useful work performed by a machine or in a process to the total energy expended or heat taken in. Efficiency is used to describe the energy that a certain system can extract and make useful from its energy source. Such systems include power plants, engines, and turbines. Any system that uses energy from a fuel or primary flow has a certain efficiency associated with it

How to Calculate Efficiency of Transmission?

Efficiency of Transmission calculator uses Efficiency = (Total Head at Entrance-Head Loss)/Total Head at Entrance to calculate the Efficiency, Efficiency of transmission is The ratio of delivered power to shaft power.It is also defined as the ratio of payload to the bitstream length. Efficiency is denoted by η symbol.
