Percent Grade Solution

STEP 0: Pre-Calculation Summary

Formula Used

Percent Grade = (Grade Resistance/(Grade Resistance Factor*Weight on Wheels))
PG = (G/(R_g*W))
This formula uses 4 Variables

Variables Used

Percent Grade - Percent Grade is a measure of the steepness or incline of a slope, expressed as a percentage.
Grade Resistance - (Measured in Newton) - Grade Resistance is the force, due to gravity, that resists the movement of a vehicle up a slope.
Grade Resistance Factor - (Measured in Newton per Kilogram) - Grade Resistance Factor is a parameter used to account for the effect of the slope (or grade) of the terrain on the resistance of soil or other materials to sliding or deformation.
Weight on Wheels - (Measured in Kilogram) - Weight on Wheels is the weight of an equipment is resting on its wheels.

STEP 1: Convert Input(s) to Base Unit

Grade Resistance: 9.99 Newton --> 9.99 Newton No Conversion Required
Grade Resistance Factor: 0.1248 Newton per Kilogram --> 0.1248 Newton per Kilogram No Conversion Required
Weight on Wheels: 20 Kilogram --> 20 Kilogram No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

PG = (G/(R_g*W)) --> (9.99/(0.1248*20))

Evaluating ... ...

PG = 4.00240384615385

STEP 3: Convert Result to Output's Unit

4.00240384615385 --> No Conversion Required

FINAL ANSWER

4.00240384615385 ≈ 4.002404 <-- Percent Grade

Rolling Resistance to Motion of Wheeled Vehicles

Go Rolling Resistance = (Rolling Resistance Factor*Weight on Wheels)+(Tire Penetration Factor*Tire Penetration*Weight on Wheels)

Weight on Wheels given Rolling Resistance

Go Weight on Wheels = (Rolling Resistance/(Rolling Resistance Factor+Tire Penetration Factor*Tire Penetration))

Total Road Resistance given Rolling Resistance and Grade Resistance

Go Total Road Resistance = ((0.02+0.015*Tire Penetration+0.01*Percent Grade)*Weight on Wheels)

Weight on Wheels given Total Road Resistance

Go Weight on Wheels = (Total Road Resistance/(0.02+0.015*Tire Penetration+0.01*Percent Grade))

Grade Resistance Factor given Grade Resistance for Motion on Slope

Go Grade Resistance Factor = (Grade Resistance/(Percent Grade*Weight on Wheels))

Weight on Wheels using Grade Resistance for Motion on Slope

Go Weight on Wheels = (Grade Resistance/(Grade Resistance Factor*Percent Grade))

Percent Grade

Go Percent Grade = (Grade Resistance/(Grade Resistance Factor*Weight on Wheels))

Grade Resistance for Motion on Slope

Go Grade Resistance = Grade Resistance Factor*Percent Grade*Weight on Wheels

Rolling Resistance when Rolling Resistance Factor is Two Percent

Go Rolling Resistance (Rolling Resistance Factor 2%) = (0.02+0.015*Tire Penetration)*Weight on Wheels

Usable Pull to Overcome Loss of Power with Altitude

Go Usable Pull = (Coefficient of Traction*Weight on Wheels)

Weight on Drivers given Usable Pull

Go Weight on Wheels = (Usable Pull/Coefficient of Traction)

Coefficient of Traction

Go Coefficient of Traction = (Usable Pull/Weight on Wheels)

Percent Grade Formula

Percent Grade = (Grade Resistance/(Grade Resistance Factor*Weight on Wheels))
PG = (G/(R_g*W))

What is Grade of Road?

The Grade of a Road is defined as a measure of the road's steepness as it rises and falls along its route. In other words, it is the magnitude of its incline or slope. The grade of a highway is a measure of its incline or slope.

How to Calculate Percent Grade?

Percent Grade calculator uses Percent Grade = (Grade Resistance/(Grade Resistance Factor*Weight on Wheels)) to calculate the Percent Grade, The Percent Grade formula is defined as the value of percent grade, which is positive for uphill motion, and negative for downhill motion.
