    Motor Parts

    @jraef The purpose of my question is to understand the motor, its parts etc.. Only for educational purposes. I could not use this table fan as one of the propellers broke and didn't feel like replacing it. @theode By looking at the picture how could you say its a 4 pole motor. I couldn't find...

    Motor Parts

    If you look at the pic, there is a small black box which has a qc-a-17 written on it. Could that be the capacitor you are talking about?

    Motor Parts

    Please have a look at the pics I have attached. It is a motor from a fan at home. I dis assembled it. I am a bit confused of the what the parts are. The one with the shaft( which is circular wheel to it)- is that the armature? And the other part which has copper wires around it , is that the...

    Max Heat input to a metal

    I have a heater which gives out 1500 Watts at full output. I have a block of metal say SS which I am trying to heat. I am trying to figure out the max temperature it will reach when the heater is used. Formula: Q=m*cp* (T(final)-T(initial)) Tinitial=25C, C(specific heat)= 0.5KJ/kg-K, m=15 kg...

    Conveyor Belt Question

    @ handleman I called the company which made these, they said they would have to do significant modifications to put a belt and its a better idea to buy a conveyor. @Ross0684, thanks for your comments. Currently my roller pitch is 3" and the roller OD is 1.873". There are currently holes...

    Conveyor Belt Question

    I do not want to buy a new conveyor belt, just looking for ideas on modifying current conveyor. Rounds bar sounds like a good idea.

    Conveyor Belt Question

    I meant its a roller conveyor. ( conveyor belt would be the ideal solution though)

    Conveyor Belt Question

    I've got a conveyor belt used for moving 5"OD annular parts. Now I want to use the conveyor belt for moving 4" OD annular parts. The problem is it gets stuck between the rollers. Now one way is to put some kind of mesh on the rollers (I haven't thought it through completely yet). Is there any...

    Testing methods for a cooling system

    The best way to go about this( according to me) is to weld on a compression fitting to the piping and measure the temperature of the liquid directly by using thermocouples. If you cant do this, You can tack weld thermocouple to the wall of the piping - inlet and outlet. Cover it with insulation...

    Impulse piping

    you can try blowing air on the tubing to transfer more heat and reduce the gas temperature. For formula, heat transfer is given by q=m*Cp*delt, m= flow rate of gas, cp = specific heat of gas and delt = 170-120=50 Once u have got the amount of heat(q) to be removed, use it in q=h*a* delt, h=...

    Heat exchanger vapourizing of water to steam

    @Chicopee- You are right, the original HX is a compact air to air and I want to run it with air-water. @25362- I haven't mentioned the purpose as it has nothing to do with the answer to my question. A few more details, I already have a model setup to predict air-air performance and it is based...

    Heat exchanger vapourizing of water to steam

    I have a counter flow air- air heat exchanger for which I know the heat transfer coefficients for various flow rates and inlet temperatures . This data is empirical data got from testing. Now on one side I want to model hot air(~800C) and the other side I want to model water(~25C). Basically I...

    Pressure tap location to measure pressure drop?

    I need to measure the pressure drop across a core( lets say a restriction). Air is flowing ( around 15 g/sec) in a 4"ID tube which is very long( irrelevant). Now there is a core ( or lets call it some restriction) in the pipe which is 10" long and around 3.92" wide which fills in the 4" tube...

    Steam Generation in Laboratory Environment

    I meant, water to be heated at atmospheric pressure, outlet to be steam at 150C with 50 C superheat. DI water is used in the process. EdStainless, would you be able to suggest and/or send some links regarding the boilers/immersion heaters you are talking about. thanks.
