The overall heat transfer coefficient of a wall is determined to be U = 0.075 Btu/h

Question:

The overall heat transfer coefficient of a wall is determined to be U = 0.075 Btu/h · ft²· F under the conditions of still air inside and winds of 7.5 mph outside. What will the U-factor be when the wind velocity outside is doubled?
