The relation of rainfall to soil moisture

Citation: Doryland, Charles. The relation of rainfall to soil moisture. Senior thesis, Kansas State Agricultural College, 1908.Introduction: The need of water, while not self-evident is at least apparent to even the superficial observer. Water is everywhere. It covers three-fourths of the surface of the earth and comprises from 40 to 95 per cent of all forms of live, while on the other hand inanimate thigs, compounds which are generally regarded as dry, may often contain a high percentage of water

Construction of one-tenth scale model of the XFV-12A and canard performance test

The XFV-12A is a high performance, VTOL, fighter/attack aircraft which incorporates ejectors in the wings and canards for thrust augmentation. During transition from VTOL to normal flight, the interaction between downflow of the lifting jets and relative flow from forward flight generates vortices distinct from airfoil circulation. These vortices are associated with the bending of the lifting jets resulting in induced velocities at the aircraft; the magnitude and influence of the vortices are unknown. The object of this thesis was to prepare a suitable one-tenth scale semi-span model of the XFV-12A for a smoke tunnel flow visualization study to explore vortex development. Performance testing was conducted on the canard augmentor, which resulted in a gross augmentation ratio of 1.34 and mass flow ratio of 6.84.http://archive.org/details/constructionofon00killLieutenant Commander, United States NavyLieutenant, United States NavyApproved for public release; distribution is unlimited
