Propellers propeller design coefficients

The most common evaporator design is based on the use of the same heating surface in each effec t. This is by no means essential since few evaporators are standard or involve the use of the same patterns. In fac t, there is no reason why all effects in an evaporator must be of the same type. For instance, the cheapest salt evaporator might use propeller calandrias for the early effects and lorced-circiilation effects at the low-temperature end, where their higher cost per unit area is more than offset by higher heat-transfer coefficients. 

Folsom lectured and contributed widely to the transactions and the scientific societies on the transportation of sand in pipelines, the design of propeller pumps and fans, the axial adjustment of deep-well turbine pumps, the performance characteristics of deep-well turbine pumps, the code for measurement of water discharges, nozzle coefficients for free and submerged discharge measurement structures, manometer errors, laboratory manuals and jet propulsion engineering. He was a member of the American Rocket Society ARS, the American Society of Engineering Education ASEE, the Aeronautical Society, and a Fellow of the American Society of Mechanical Engineers ASME.
