I'm a mechanical engineer trying to measure power input to a 150kW motor. The power factor of the plant to which the motor is also connected is known to be low at present (without the motor running). The motor is probably a major proportion of plant load when operating. The nameplate PF for...
Hi
I am looking for ideas to improve corrosion/erosion protection of an ID fan impeller following a wet scrubber on a sugar mill boiler (there is some erosion as well as corrosion). The flue gases are saturated at around 50C.
I am looking for a paint or coating system. The impeller is made...
Does anyone have experience with motors seizing due to contact with the inner flame path housing in the event of a bearing failure. I am trying to assess if this is a common problem.
I am looking for data on diffuser loss when there is swirl present in the airflow. There is a great deal of data on diffusers with non-swirling axial flow but I can't find anything with swirl present.
Can anyone point me to where I might get some design data for PVC pipe used as structural members. For example the torsional strength of cemented fitting joints. I can find general but limited data on material properties and plenty on pressure capability etc but not much about structures.
Hi
Does anyone have a table or link giving values of Youngs Modulus for general purpose structural steel eg. A36 at elevated temperatures up to about 300C. ISO or English OK.
Does anyone know of a low cost program for calculating shaft critical speed. Ideally one that takes support stiffness into account as well as being able to input various masses and shaft diameters.
I would appreciate if anyone can give me some guidance - especially an approximate overall heat transfer coefficient - for a simple heat exchanger comprising oil in plain stainless steel pipes cooled by air blown across them. Stainless steel is used because of corrosion. I am aware of its poor...
I would like some formulae for estimating loads produced by a 1:1 mitre bevel gear. I have read texts that give data for straight cut bevels but am interested in what effect if any the spirol has.
I am trying to individually give all parts the same customised color in an assembly but things don't seem to work as expected. Sometime colors don't want to change and the online help hasn't given me the answer. Can someone help? Although it isn't something that I do regularly I don't recall...
