A study was conducted in which water was pumped through cylindrical pipes made of a sparingly soluble solid. For a given pipe and certain flow conditions, the mass transfer coefficient k_c has been calculated as 1 mm/s using the correlation

Sh = 0.025 Re^0.6 Sc^0.33

If the velocity of the fluid and the diameter of the pipe are both doubled, what is the new value of k_c in mm/s, up to 2 digits after the decimal point? ____________

1.14 to 1.16

1.45 to 1.46

2.34 to 2.35

5.43 to 5.44
