ISSUED:
September 1995
REVISED:
July 1996
PRODUCT:
Centaur 40, Centaur 50 and Taurus 60
MODEL(S):
All
Specifics:
Pneumatic start, gas fuel or dual fuel systems
SUBJECT: NEW STRAINERS FOR PNEUMATIC START AND
NATURAL GAS FUEL SYSTEMS
—REVISION NOTICE—
Includes Centaur 40 in the product category.
Type of Change:
Product Improvement
Recommended
Compliance:
Immediate
Purpose:
To announce the availability of a new standardized 2", 200 mesh strainer, Part No. 120401-16, for
pneumatic start and gas fuel supply lines.
GENERAL INFORMATION:
Contamination within the pneumatic start system has been responsible for several instances of pre-
mature wear and turbine starter failures. Turbine starter life can be significantly improved by re-
placing the 100 mesh strainers, previously supplied as part of the loose ship kit for pneumatic start
systems, with a new 200 mesh strainer. Installation of a second 200 mesh strainer is recommended
for natural gas fuel systems and dual fuel systems. All systems now use the same part number
strainer assemblies.

NUMBER: 2.1/106A
RECOMMENDED ACTION:
1.
Two 2", 200 mesh pneumatic system strainer assemblies, Solar part no. 120401-16,
should be ordered from your local Solar parts sales representative.
2.
Locate the 2" strainers currently installed in the pneumatic start system and the natural
gas fuel supply line. The strainers are normally installed outside the skid at the point
where the gas enters the skid connections (see Figure 1 and Figure 2).
3.
Shut the package down and close the hand valve located upstream of the strainer. Ensure
no gas pressure is present in the vicinity of the pneumatic strainer.
4.
Remove the entire strainer assembly including the housing and install the new 2", 200
mesh assembly.
5.
After completing the installation and ensuring proper connections, open the hand valve
and check for leaks.
6.
Restart the package, and continue normal operation.

True Story! The 1998-1999 Mars Climate Orbiter mission was declared a total loss in1999 as there was a unit conversion mismatch error between Lockheed Martin and NASA. Themismatch was in the thruster force units. NASA used the SI system which called forNewton-Seconds (4.45 times as large) of thrust and Lockheed Martin used Pound-Force Seconds.Calculations placed the Orbiter at 68 miles from the surface as it went into orbit, but it waswithin 57 km of the surface after the breaking maneuver. Any distance from the surface lessthan 50 miles would have caused the Orbiter to crash.a. What was the actual distance of the Orbiter from the surface in miles?b. In percentage, how far off from the calculated 68 miles was the Orbiter?

Q1:
A. One of the researchers discovered a patent related to the development of a
certain software module in mobile devices, and when he emailed one of the
companies producing these devices, they asked him to send the research to try it on
their devices, and after a while this researcher discovered that his discovery was
used by this company without referring to him or buying this discovery, What do
you think about the above.
B. As a quality control engineer in one of the electrical appliance factories, I
discovered that the technical worker responsible for inspecting one of these
products seals its validity without inspecting it. when I filed a complaint with the
administration, the administration neglected the complaint, arguing that there was
no time to inspect it again due to lack of time to prepare the consumer.

Problem Statement
=
You install a heat pump to heat a cottage during the winter using the outside air as the heat
source. You wish to maintain the interior temperature of the cottage at 22°C. A simplified
model of the heat loss through the walls indicates that heat will need to be supplied at a
rate of 0.14(Tinterior - Texterior) where Q is the rate at which heat must be supplied to
the cottage (in kW), Tinterior is the interior air temperature (in C), and Texterior is the exterior
air temperature (in C). You have a 1kW electric motor available to run the heat pump.
What is the coldest winter day when the heat pump will be able to keep up to the heating
demand?
