ELONGATED BODY OF REVOLUTION 



A quarter body of an elongated body of revolution was mounted on the side wall of the 

 tank in the same manner as the sphere. The body chosen was one for which the velocity and 

 pressure distribution had been determined by the theoretical method developed by 

 Landweber. ^^ The equation of the body is 



y2 =0.04(1 -r'') [19] 



The model was made of wax with a length of 20 in. and a midsection radius of 2 in. The 

 micrometer screws for x and y motions of the carriage had been added to the tank when this 

 model was studied, but other improvements had not been made.
