TP24-03 Characterization of Elliptical Pitot Tube for Water Flow Measurements HVAC Applications

TP24-03 Characterization of Elliptical Pitot Tube for Water Flow Measurements HVAC ApplicationsIn 2018, CTI switched from simplex pitot tubes to an elliptical style pitot tubes for water flow measurements. This change was made to reduce the impact of change in Reynolds number on the calibration coefficient of the pitot tube. In addition, the new design incorporated a one inch (1) round body to reduce the vibration of the pitot. In this process, the blockage area of the pitot probe was increased. McHale has performed calibration studies at three

Let us go through this same exercise on an air conditioning unit

Many water treatment chemists overlook the impact of other parameters upon pH and thereby their impact upon important values and constraints such as scaling indices and inhibitor activity

and the results of some of the measurements taken during the first year of activity

The main target of these R&D efforts was and is the improvement of the evenness of water distribution in cooling towers and consequentially the overall cooling performance

3: The importance of proper water balancing between existing and supplemental cells/towers

Cooling tower testing is based on the wet bulb psychrometer

Evaporative pre-cooling of air cooled heat exchangers provides the thermodynamic advantages of water cooling towers with the reduced maintenance requirements of air cooled heat exchangers

monitoring is usually conducted after a problem develops

This paper will deal with the preparation of specifications for cooling water treatment in grass-roots plants of this type

Collectively

The State and Federal regulatory bodies are expected to sanction control stand­ards that will negate the use of chromates and zinc without acceptable disposal methods

This paper provides guidance for equipment designers to match the water quality with the compatible materials of construction
