Question

the voltage is 20v, amperage is 100a, and travel speed is 10 ipm.

hi = \frac{voltage \times amperage \times 60}{travel speed}

what is the heat input in joules per inch?

120 j/in
1200 j/in
12,000 j/in
120,000 j/in

Explanation:

Step1: Substitute the given values into the formula

Given Voltage \( V = 20V\), Amperage \( A=100A\), Travel Speed \( S = 10\ ipm\).
The formula for \(HI\) is \(HI=\frac{V\times A\times60}{S}\).
Substitute the values: \(HI=\frac{20\times100\times60}{10}\).

Step2: Calculate the numerator first

Calculate \(20\times100\times60\):
\(20\times100 = 2000\), then \(2000\times60=120000\).
So the expression becomes \(HI=\frac{120000}{10}\).

Step3: Perform the final division

\(\frac{120000}{10}=12000\).

Answer:

12,000 J/in
