Variation in Velocity Profile with Change in Surface Roughness of Boundary

Variation in Velocity Profile with Change in Surface Roughness of Boundary

Date: September 1, 1940
Creator: Jacobs, W
Description: The present report deals with the variation of a turbulent velocity profile in flow from rough to smooth wall and vice versa. Expressions obtained for the shear-stress distribution with respect to the distance from the point of junction of the different roughnesses and from the wall distance, are utilized to ascertain the developing velocity distributions. Under simplified assumptions, the use of these formulas renders possible the integration of the motion equations for the shear stress. This calculation is carried out and compared with the experiments.

The Wheat Jointworm and Its Control

The Wheat Jointworm and Its Control

Date: 1940
Creator: Phillips, W. J. (William Jeter), 1879-1972 & Poos, F. W.
Description: Revised edition. "The wheat jointworm is a very small grub which lives in stems of wheat, feeding on the juices of the plant and causing a slight swelling or distortion of the stem above the joint. The egg from which it hatches is laid in the stem by an insect resembling a small black ant with wings. This insect attacks wheat only. The injury which it causes to wheat is very distinct from that caused by the Hessian fly, yet the effects caused by these two insects are often confused by farmers." -- p. 1-2. This bulletin gives a brief outline of the life cycle and the nature of the injury to the plant by the jointworm so that any farmer may readily recognize its work and be able to apply the measures of control herein recommended.
