Minimum milk requirement for calf raising

Submitted in partial fulfillment of the requirements for the degree of Master of ArtsThe dairyman is keenly interested in knowing how he can raise his calves in an economical and successful manner. This thesis reports the results of several experiments in early weaning and minimum use of milk for calf rearing, which constitute part of a plan for making a thorough study of the problems involved in the early growth and development of dairy heifers. The review of literature embodies a resume of published data on the subject, as well as a survey of what has been written on the newer factors influencing growth and their application to practical feeding operations.Includes bibliographical references

The Effect of the Liquid Viscosity in Two-Phase, Two-Component Flow

An evaluation was made of the effect of the liquid-phase viscosity on slip ratio using a forced-circulation two-phase two-component system operating at atmospheric pressure for air and glycerol-water mixtures. The effect of liquidphase viscosity on pressure drop was observed, and the flow regimes were identified and studied. The approximate ranges of the variables investigated were: liquid viscosity, 0.75 to 500 cp; quality, 0.005 to 0.0184; liquid flow rate, 0.2 to 0.8 Ib/sec; air flow rate. 0.001 to 0.015 Ib/sec; and void-volume fraction, 0.34 to 0.78. The vold-volume fraction and the approximate distributlon of the two-phase mlxture at a particular cross-sectional element of the test section were determlned by -attenuation techniques. The slip-ratio and pressure-drop results were not found to Indicate any considerable variations caused by changes in flow pattern or liquid flow rates for the range of flow conditions and liquid viscosities encountered.
