How to Calculate Temperature & Time of Heating Element

  1. Nov 1, 2007 #1
    Heating Wire having the following Data :
    SWG 16(1.63mm)
    Specific Resistivity = 1.45 ohms-mm-3
    Density = 7.1 gm-cm-3
    Resistance = 0.685 ohms/Meter
    Weight = 15 Gram/Meter

    (a)Please help me in this Project to Build Heating Element using the above wire for Making 2.5 KiloWatt heating Element
    (b)Please help me in this Project to Build Heating Element using the above wire for Making 3.5 KiloWatt heating Element

    Take ambient & room temperature as 35 degree Centrigrade.
    How to Calculate the following :
    (a)Please state the formula for Calculating Temperature Raised in 1 hour ?
    or alternately What would be temperature of heating element after Heating Element heated for 1 Hour?

    (b)Please State the Formula for Calculating, How Many Calories of Heat in generated in 1 hour?
    (c)Say if the Temperature is raised till (i)800 degree Centigrade what would be the Kilowatt generated & in what time this Temperature would be raised?

    (c)Say if the Temperature is raised till (ii)1000 degree Centigrade what would be the Kilowatt generated & in what time this Temperature would be raised?

    Please state the explaination using formulas.
    ThankX in Advance
    Awaiting your valued Calculations
