Propulsive power Solution

STEP 0: Pre-Calculation Summary

Formula Used

Propulsive Power = 1/2*((Mass Flow Rate+Fuel Flow Rate)*Exit Velocity^2-(Mass Flow Rate*Flight Speed^2))
P = 1/2*((m_a+m_f)*V_e^2-(m_a*V^2))
This formula uses 5 Variables

Variables Used

Propulsive Power - (Measured in Watt) - Propulsive Power refers to the power generated by a propulsion system.
Mass Flow Rate - (Measured in Kilogram per Second) - Mass Flow Rate represents the amount of mass passing through a system per unit of time.
Fuel Flow Rate - (Measured in Kilogram per Second) - Fuel Flow Rate refers to the rate at which fuel is supplied or consumed within a system over a specified period.
Exit Velocity - (Measured in Meter per Second) - Exit Velocity refers to the speed at which gases expand at the exit of nozzle of a engine.
Flight Speed - (Measured in Meter per Second) - Flight Speed refers to the velocity at which an aircraft moves through the air.

STEP 1: Convert Input(s) to Base Unit

Mass Flow Rate: 3.5 Kilogram per Second --> 3.5 Kilogram per Second No Conversion Required
Fuel Flow Rate: 0.0315 Kilogram per Second --> 0.0315 Kilogram per Second No Conversion Required
Exit Velocity: 248 Meter per Second --> 248 Meter per Second No Conversion Required
Flight Speed: 111 Meter per Second --> 111 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P = 1/2*((m_a+m_f)*V_e^2-(m_a*V^2)) --> 1/2*((3.5+0.0315)*248^2-(3.5*111^2))

Evaluating ... ...

P = 87038.938

STEP 3: Convert Result to Output's Unit

87038.938 Watt -->87.038938 Kilowatt (Check conversion here)

FINAL ANSWER

87.038938 ≈ 87.03894 Kilowatt <-- Propulsive Power

What is propulsion?

Propulsion is the action or process of pushing or pulling to drive an object forward. Propulsion system consists of a source of mechanical power, and a propulsor (means of converting this power into propulsive force).

How to Calculate Propulsive power?

Propulsive power calculator uses Propulsive Power = 1/2*((Mass Flow Rate+Fuel Flow Rate)*Exit Velocity^2-(Mass Flow Rate*Flight Speed^2)) to calculate the Propulsive Power, Propulsive power is a measure of the energy required to produce movement or thrust, typically in a vehicle or aircraft, which is affected by the masses of the object and fuel, as well as the velocity of the exhaust gases. Propulsive Power is denoted by P symbol.

How to calculate Propulsive power using this online calculator? To use this online calculator for Propulsive power, enter Mass Flow Rate (m_a), Fuel Flow Rate (m_f), Exit Velocity (V_e) & Flight Speed (V) and hit the calculate button. Here is how the Propulsive power calculation can be explained with given input values -> 0.087039 = 1/2*((3.5+0.0315)*248^2-(3.5*111^2)).

FAQ

What is Propulsive power?

Propulsive power is a measure of the energy required to produce movement or thrust, typically in a vehicle or aircraft, which is affected by the masses of the object and fuel, as well as the velocity of the exhaust gases and is represented as P = 1/2*((m_a+m_f)*V_e^2-(m_a*V^2)) or Propulsive Power = 1/2*((Mass Flow Rate+Fuel Flow Rate)*Exit Velocity^2-(Mass Flow Rate*Flight Speed^2)). Mass Flow Rate represents the amount of mass passing through a system per unit of time, Fuel Flow Rate refers to the rate at which fuel is supplied or consumed within a system over a specified period, Exit Velocity refers to the speed at which gases expand at the exit of nozzle of a engine & Flight Speed refers to the velocity at which an aircraft moves through the air.
