Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1914 edition. Excerpt: ...readings the wind velocities must have varied so as to give a reasonable indication of the effect of the wind velocity on results obtained. Attention is called to the fact that in some cases the water leaving the tower reached the temperature of the wet bulb thermometer. Particular attention is called to the condenser pressures, which were never greater than I90 pounds and averaged considerably below. Louis Bl0ck.--I want to ask Mr. Coffey or Mr. Horne what influences the cooling most, the wind, the movement of the air or the wet bulb? B. H. C0fiey.--I think the wet bulb has the more effect. Louis Bl0ck.--All those figures which we have heard just now from Mr. Burhorn and Mr. Coffey give us temperatures, but never volumes. With the cooling tower we can cool from I56 degrees d-own to the wet bulb by running a small quantity of water over it; but, when the quantity of water is run over the tower for which it was built, then it is a question of how close to the wet bulb we will come. Neither one of these gentlemen has given us that. George A, H0rne.--I am very glad that Mr. Block brings out that point, because, perhaps, it was not conspicuously brought out in the text, but in the case of all these tests the quantity was held practically to within a few gallons of the rated capacity of the tower. We circulated all the water we could cool. It was within a very few gallons of the rated capacity and varied from 740 to 800 gallons per minute. It should have been more explicitly stated, because some of the figures given in the recent criticism of Mr. Burhorn have failed absolutely, as Mr. Block states, to mention quantity of water. Speaking as a purchaser, as well as an engineer, I want to say that most all the tests that have come to my attention...show more
