Advice,Affiliate Programs,Automotive Parallel and series connected blower installations are often used to meet performance ranges beyond normal single stage blower capacities. For systems that require high ststic pressure, and especially high pressure TOGETHER with high temperature (where standard multi stage, positive displacement, screw, or regenerative type blowers can not be used) series of single stage centrifugal blowers can be used. Many times additional blower in the system can be advantageous. For instance, where two blowers are operating in series and one breaks down, the other may be able to "limp" the system along while the necessary maintenance is performed. Having on blower continue in operation can often allow limited production while the other is being repaired. Also, there are cases where having one blower continue in operation could prevent or at least minimize system or equipment damage from such things as high temperature ot contaminated airstreams.

Another advantage of blowers in series is that of the availbale space. If system must be expanded and increaases the CFM requirements, the allotted space for the original blower may not be large enough for a single large blower, but might be large enough to istall two smaller blowers in series to obtain the necessary pressure.

One potentail advantage for series operation is the likehood of initial cost savings. Although each case must be evaluated individually, it is Carbon steel screw often more economical to select two "smaller" blowers with their respectice smaller motors and drives than to select one "larger" blower to do the job.

Series connected blowers are those which have the outlet of the one blower exhausting into the inlet of another blower. By connecting blowers in such a manner, high static pressures can be attained. This is accomplished as the second blower adds its pressure capability to the system, increasing the capacity beyond the capabilities of the first blower.

Ideally, two identical blowers installed in series would result in the same CFM at the outlet of the second blower as the inlet of the first one, and nearly twice the static pressure as that rated for either blower alone. However, some variation will result in both air flow and combined pressure because of the tendency of air to compress under pressure. A good understanding of how atnoshperic pressure and absolute temperature affect density is required. Both of these factors are involved in the proper selection of blowers. Density is directly proportional to atmospheric pressure and is inversely proportional to absolute temperature (degrees Rankine).

Caution is necessary in selecting blowers for series installtion. It is generally accepted that most pre-engineered blowers are capable of withstanding twice their catalog rated static pressure. In other words, where two blowers are installed in series the second blower housing should withstand the higher pressure. There is, however, a need for concern when the combined pressure exceeds twice the rated static pressure for one blower. In series applications involving three or more blowers, or in any system in which positive or negative pressure exists prior to the consideration of the blowers, special housing reinforcement may be necessary.

Some babies that aren't started on solid foods by the age of 9 - 12 months may have a great level of difficulty accepting solid foods. When a baby seems to get hungry or once weight gain isn't continuing at the desired rate, it may be good to start solid foods as early as 3 months. Allow your baby to enjoy the food and don't worry too much about how much he takes at first, as much of it may end up on the floor or in his hair anyhow.When the baby starts to reach for food, it's normally the time to go ahead and give him some.Breast milk is all your baby will need until at least 4 months of age. Full term babies will start to require iron from other sources by 6 - 9 months of age. The easiest way to get iron for your baby at 5 - 6 months of age is by giving him meat. When to start The ideal time to begin solid foods is when the baby shows interest in starting. You should however, avoid spicy foods or highly allergenic foods at first, although if your baby reaches for the potato on your plate, you should let him have it if it isn't too hot. Sometimes, it may be a better idea to start food earlier. It's actually a developmental milestone when your child starts solid foods - as he is now growing up. There does come a time, when breast milk will no longer supply all of your baby's nutrition needs. Some babies will show interest in solid food when it's on their parents' plates, as early as 4 months of age. Breast fed babies will digest solid foods better and earlier than artificially fed babies because the breast milk will contain enzymes which help to digest fats, proteins, and starch. It may be possible however, to continue breast feeding alone and have the baby less hungry or growing more rapidly. Offer your baby the foods that he seems to be interested in. Introducing solid foods When the baby begins to take solid foods at the age of 5 - 6 months, there is very little difference what he starts will or what order it is introduced. Cereal for infants has iron, although it is poorly absorbed and may cause your baby to get constipated
