Steady-state creep rate data are given in the following table for some alloy taken at 200C (473

Question:

Steady-state creep rate data are given in the following table for some alloy taken at 200°C (473 K):

s (h-1) __________________ ( [MPa (psi)]

2.5 × 10-3 .......................... 55 (8000)

2.4 × 10-2 ........................ 69 (10,000)

If it is known that the activation energy for creep is 140,000 J/mol, compute the steady-state creep rate at a temperature of 250°C (523 K) and a stress level of 48 MPa (7000 psi)?
