I've heard so many rules of thumb over the years, it was interesting
to find this excerpt from the Carbon Trust suggests the following..
The size of an air receiver will depend on the amount of fluctuation
in air demand. In most cases an adequately sized receiver will be able
to supply the extra air during a high demand period and then recharge
when the demand drops off. This function allows the air compressor to
be sized for the average demand, rather than for the maximum demand.
In some cases when the fluctuation is too great, a solution can be to
have a smaller compressor that can kick in as required.
There are a number of formulae for calculating the storage volume
required. However, the following empirical rule can provide an
approximation for planning purposes, taking into account the compressor
(s) output and the pattern of demand.
The Air receiver should be sized (in Litres) to be at least 6 10
times the compressor free air output (in litres/s)
It is also worth considering the following:
To provide optimum performance, the receiver should be sized for the
largest expected air demand event.
An undersized receiver will cause the compressor to cycle frequently
in response to small changes in pressure.
An oversized receiver will cost more and will store more air, but it
will require the compressor to remain on load for longer periods to
recharge the air receiver. This is balanced by the extra time the
compressor will have to cool before it must come on load again.
The volume of the pipe work is often significant but is not included
in the calculations.
An effective control system will ensure that the receiver volume
balances the demand from the system with the supply from the
compressor.

[/quote:89a551566b]
One major international compressor manufacturer recommends one
receiver (with extensive condensate drain) of about 1/8 the
output volume in a minute on the compressor side of the filter,
and one sized as you say downstream of them. That way the
filtration is not a hindrance for meeting air demands.
Of course their compressors modulate infinitely... from "0" to
full output.

HOW DID THE SPREAD OF ISLAM AFFECT THE WORLD?
Please forgive us for any disturbance, but we have an important
subject to address to you regarding FAITH, and we Dont intend to
overload your email with unnecessary
messages
HOW DID THE SPREAD OF ISLAM AFFECT THE WORLD?
Among the reasons for the rapid and peaceful spread of Islam was the
simplicity of its doctrine - Islam calls for faith in only one God
worthy of worship. It also repeatedly instructs people to use their
powers of intelligence and observation. Within a few years, great
civilizations and universities were flourishing, for according to the
Prophet, "seeking knowledge is an obligation for every Muslim."
The synthesis of Eastern and Western ideas and of new thought with
old, brought about great advances in medicine, mathematics, physics,
astronomy, geography, architecture, art, literature, and history. Many
crucial systems such as algebra, the Arabic numerals, and also the
concept of the zero vital to the advancement of mathematics, were
transmitted to medieval Europe from Islam. Sophisticated instruments
which were to make possible the European voyages of discovery were
developed, including the astrolabe, the quadrant and good navigational
maps

Appealing to any sort of moral code does not work. Ministering
the words of Jesus Christ (or was it Paul?) did not work. So
let's try this...
