The pressure just inside the radiator-tube entrance, unlike the temperature, is not uniquely determined by the-airplane speed and the tube-entrance velocity.
Values of airplane speed, altitude, and tube-entrance velocity ale assumed.
Lines of constant tube-entrance velocity have also been plotted in figure 3 to- aid in the quick- determination .of.the. cooling-air quantity at the radiator face...
Figure 4 shows the drag characteristics of the radiators as functions of the flight speed, the heat-transfer rate, and the tube-entrance velocity.
The ratio; of the drag . power to the heat-transfer rate may be determined from figure 4(a) from the values-of 'the airplane speed, the tube-entrance velocity, and the altitude.fu.Tb(c).
