Question

How many kilopascals are there in 1 kg/cm^2?

(a) 89 kPa

(b) 76 kPa

(c) 98 kPa

(d) 69 kPa

I have been asked this question at a job interview.

My doubt is from I.C Engine topic in section Internal Combustion Engine of Farm Machinery

Answer 1

The correct choice is (c) 98 kPa

Explanation: 1 kg = 9.8 N

1 N.m. = 1 Joule

1 N. m/s = 1 Joule/s = 1 Watt

1 kg/cm^2 = 9.8 * 10^4 N/m^2 = 9.8 * 10^4 Pa = 98 kPa
