DEAR MECH ENGINEERS
CAN I ASK YOU
whats the rank of catia between other softwares
such as solid works and solid edge and pro eng and inventor
and if its possible tell me
is catia the most effieicnt between them and is it enough for any mechanical engineer or its like other software has...
dear friends i have an application for pumping system
it consists of 3 parallel pumps having a max head of 8 bars
i have a stainless steel pipe has 8" diameter and sch 10
will this be suitable to be used under this pressure ?
accordin to my last to posts here i found this special pump which has materials designed to carry a high press but the problem now
i found a pump on the machine is bigger than the one in the manual
so shall i buy the pump from manual or as the existing pump ?
tell me guys whats the relation between Hms and Hmd and the pump selection for example
i have Hms =10bar , Hmd =12 bars so Hm =2 bars
so the Head of the pump is only 2 bars or its said that
pump has a head of 2 bars and can withstand 12bars ???
how are u ??
i ve a problem with selecting a centrifugal pump for circulating water in a closed system this system consists of tank , pipes up to 60 meters with 2 inch dia , then these pipes deliver water to a tube contains pressurized nitrogen @ 10 bars then return back to tank and...
hello everyone i am a maintenance engineer in old factory so while we were working on an old machine yesterday we found a very strange gear box like the harmonic drives but it transmitts the motion from the motor shaft by a key to bearings those bearings transmitts motion to a elliptic shaped...
i have a system consists of a shell an tube exchanger and a centrifugal blower the blower suction is at the exit of the exchanger
i want to replace the shell and tube with a multi plates heat exchanger
whats my conditions for this process
max press 16 bar
mechanical engineer :D or :S
well i am a mechanical engineer in a factory my job is maintenance of different machines so i am dealing with many mechanical systems
also dealing with air compressors pneumatic circuits , hydraulic circuits and air chillers i deal with many things may be...
hello guyz i have some questions about shell and tube exchangers
1- whats the difference between shell and tube exchanger over the plate exchanger ??
2- whats the data required for selecting heat exchanger ??
3- if i will replace the shell and tube with a plate exchanger whats the...
2 identical parallel centrifugal pumps ???
hello everyone i have a very confusing problem with a cold water system sonsists of 2 identical centrifugal pumps their position is under the tank so there is always a +ve suction head then those pumps takes water from the tank and deliver it to a...
