- Homework Statement
- An equation for the forced convection heat transfer coefficient over oval shapes is h = 12.5*v^0.6 where v = 5 +/- 0.6 m/s (95% confidence interval). Calculate the percentage uncertainty (95% CI) in the value of the convection heat transfer coefficient, to 1 d.p.

- Relevant Equations
- h = 12.5*v^0.6

This is from an online quiz. I thought the answer would be

0.6/5 = 0.12

0.12*0.6 = 0.072

∴ 7.2%

but apparently this is wrong. Can anyone help me out please?
