电加热器的设计资料

一、常用计量单位
    1.功率:W、KW
       1KW=3.412BTU/hr(英热单位/小时)
        =1.36(马力)  
        =864Kcal/hr  
    2.重量:kg
       1kg=2.204621b(磅)
    3.流速:m/min    
    4.流量:m3/min、kg/h    
    5.比热:Kcal/(kg℃)
       1kcal/(kg℃)=1BTU/hr.oF=4186.8J/(Kg℃)
    6.功率密度:W/cm2
       1W/cm2=6.4516 W/in2
    7.压力:MPa
    8.导热系数:W/(m℃)
       1 W/(m℃)=0.01J/(cm s℃)=0.578Btu/(ft.h.F)
    9.温度:℃
       1oF=9/5℃+32  
       1R=9/5℃+491.67  
       1K=1℃+273.15
    二、功率密度的选择
