Question

Convert

1 Mpa/sec = ? kN/mm2/min

Answer 1

Mpa = mega pascals = 10^6 pascal

1 Mpa/sec = ? kN/mm2/min

1 Pa = 1 N / m² ≡ 1 kg / m

1 X 10^6 pascal = 1x 10^6 N/m^2

1x 10^6 N/m^2/sec x 60 sec/min = 60 x 10^6 N/m^2/min

60 x 10^6 N/m^2/min x 1m/1000mm x 1m/1000mm = 60 x 10^12 N/mm^2/min

60 x 10^12 N/mm^2/min x 1kN/1000N = 60 x 10^9 = 6.0 x 10^10 kN/mm^2/min
