- What is the Euler load?A compressor that has been in service for 20 years has finally broken down beyond repair, and now must be replaced. The old 180hp machine cost $1200 and its cost index at that time was 144.5. The new machine will be 400hp. How much will the new machine cost, given that today's compressor index is 252.4 and the power-sizing exponent for compressor sizing is 0.32? A: $929 B: $2706 C: $1434 D: $2096 E: $1549Problem 8.2 The power source characteristics is given by I²=- 350 (V – 90) and the volt- age-length characteristics of a DC are is expressed by V = 25 + 51, where I is the arc length in mm, and V is the are voltage. Find the change in welding current for a change in arc length from 5 mm to 7 mm.
