Structures are generally regarded as having many attributes, including: 1) are self-supporting, 2) have the capacity to support gravity loads, and 3) have the capacity to resist seismic forces imposed at their base. Building codes historically are mo

SUMMARY1. The feed intakes of 18 Ayrshire cows continuously grazing a timothy-meadow fescue-white clover sward were estimated by the chromic oxide-faecal nitrogen method for two 6-weekly periods, one in 1960 and one in 1961. The cows consisted of (1)

1. Two experiments each with 3 dry cows, 3 heifers and 3 calves were carried out in 1959 and 1960 under uniform continuous grazing conditions on a ryegrass-white clover sward to measure individual feed intake by the chromic oxide-faecal nitrogen meth

Local heat-transfer coefficients and recovery factors have been determined for an elliptic cylinder of 1:4 axis ratio at zero and at a 5-deg angle of attack in an air stream. These results are presented for Reynolds numbers from 607,000 to 1,330,000,

Many applications of heat-transfer phenomena by forced convection require a knowledge of heat transfer from simple geometric bodies like the flat plate. Investigations of the flat plate have been limited, in general, to studies of isothermal plates o

Local heat-transfer coefficients and thermal-recovery factors from a 1:3-axis-ratio elliptical cylinder to air are presented for angles of attack of +6 deg, 0 deg, and −6 deg with reference to the wind-tunnel center line. Air speeds ranged from 150

An approximate analysis is presented for the prediction of the over-all average heat-transfer coefficients from spheres to air in the transition-flow region, that region wherein the mean free molecular path is small but not negligible when compared w

Free-convection heat-transfer coefficients have been measured on a horizontal circular cylinder to Freon 12 near the critical-state conditions as a function of the temperature difference between the test cylinder and the Freon environment. Experiment
