entire grain pressure being transmitted to the fluid. This initial pressure, of course, 

 which required counterbalancing by a certain amount of grain placed in the bin, 

 was taken due account of in the computations."

 and corn are shown diagrammatically. These show that, wdiile the measurements 

 with the pressure gage are of doubtful value for decreasing pressures, they afford a 



g I indication of degree of pressure increase during emptying. There was a "very 



satisfactory agreement between the calculated and the observed pressures."
