Correlation Of Weir Crest Depth, Froude Number, H/P Ratio, Weir Thickness, Paul Harrawood
Correlation Of Weir Crest Depth, Froude Number, H/P Ratio, Weir Thickness, Paul Harrawood
Masters Theses
"1. The Froude number criterion for weir flow was shown to be sound and accurate by experimental verification of the theoretical correlation of Froude number and critical depth. It was proved that sub-critical, critical and super-critical flows are correctly identified by the Froude number.
2. In order to accurately determine the Froude number, the actual flow section at the weir crest must be known. Because of end contractions, it does not have the same dimensions as the weir opening. For the Cipoletti weir, it is the product of the length of the crest and the crest depth, i.e., A= by. …
Determination Of The Effect Of Air-Entraining Agents On Certain Physical Properties Of Concrete At Early Ages, James Arthur Spilman
Determination Of The Effect Of Air-Entraining Agents On Certain Physical Properties Of Concrete At Early Ages, James Arthur Spilman
Masters Theses
"Air entrained concrete over the past eighteen years has received national recognition as a result of its satisfactory performance in highway concrete pavements and other concrete structures subjected to outside exposure.
Numerous highway departments over the entire United States have laid test slabs made of air entrained concrete. Among those to date are Pennsylvania, New Jersey, New York, Connecticut, Massachusetts, Vermont, Maine, Illinois, Missouri and California. The primary purpose in building these test slabs was to investigate their durability or resistance to freezing and thawing and the action of various salts on air entrained concrete. The results of the test …

"One of the principal types of heavy duty pavements in use in Missouri and in many other states is that known as rigid type portland cement concrete.
There have been two major trends in this type of pavement design. One of these trends is the use of short slabs, i.e., 15 to 25 feet, with no reinforcement. Another trend consists of concrete slabs containing distributed reinforcement such as wire mesh or reinforcing bars with joints occurring at fairly large intervals of 50 to 100 feet. As loads on the highways have increased the designers have increased the slab thicknesses and …
