Now see table on next page. 



The above, of course, is for standard density air. 



Ceiling. The curves for P T , P R , and P on V just determined 

 are plotted on page 192, and the throttling curves are plotted 

 across them (the plotting of the throttling curves is only necessary 

 in order that they may appear in print : in actually making such 

 a calculation as this, one only has to lay the celluloid curves over 

 the squared paper, of course). 



The engine being a stationary one, q = "839, and/ = -161, 

 of course. 



Now V is the Air Speed Indicator reading for which the
