American Society of Heating and Ventilating Engineers Guide, 1934 following formulae may be used to determine an equivalent wind velocity to be used in connection with Tables 1 and 2 that will allow for both wind velocity and temperature difference: Ate = V M* -- 1.75 a (1) where Me = VJM5 + 1.75 b (2) Me = equivalent wind velocity to be used in conjunction with Tables 1 and 2.
