Temperatures in Troposphere
of standard atmosphere in Troposphere (Altitude less than 11
kilometers or 36,089 feet from sea level) at various heights
during the landing approach by two commercial aviation jet flights
were calculated as a general indication and compared with the
actual flight data displayed for passangers. The Troposphere
layer of the atmosphere receives the radiation of surface absorption
of solar energy, which reduces the temperature decrease from
a perfect adiabatic flow expansion modeling for hydrostatic
pressure. The model compares well the Troposphere temperature
gradient published by the National Space and Science Data Center
(NSSDC)1976 for the Standard Atmosphere. But both have a maximum
of 15 to 20 degF deviation from the reported data especially
at higher altitudes.
location's actual weather conditions at various altitudes should
also contribute to the outcome of calculation for the "Non-Standard
Water Decoupler / Hydraulic Separator
chilled water is to be recycled for economic reason. Due to
the nature of highly variation in loads of a HVAC system principally
due to the ambient conditions, and for the purpose of maintaining
a mechanical efficient operation of the Chiller and Pumps, it
becomes objective to operate the primary and the secondary circuits
at their respective optimum design flow conditions. The need
for this flexibility in deploying equipment or in operation
leads to a need of segregation or decoupling of the primary
and secondary flow rates. This tie-line (i.e., the decoupler)
effectively creates two connecting piping loops. This can be
illustrated in Fig. 1.
like a pipe decoupler, a separator also can be used to prevent
hydraulic coupling of pump flows in a primary-secondary chilled
water piping configuration. Thus, a separator acts as a hydraulic
bridge between the primary and the secondary circuits.
of Flow in Small Machinery
surface wetness and oil passage are important to prevent the
bearing from overheating. In one project we developed
mathematical models for analysis of oil passages and leakage
in a micro bearing system.
