Salamander Ceramic Infrared Emitters Technical Manual Page 19 Water Evaporation Example (continued): Warm-up Time: Warm-up Time = __________________ x 60 Minutes Watt / in2 (22.6 x 10-3) 5/60 min. = ________________ x 60 Watt / in2 Solve the "time" equation for Watt / in2: (22.6 x 10-3)(60) Watt / in2 = __________________ = 16.27 (5/60 min) The effective emissivity between two parallel plates is given by: 1 1 e = __________________ = ___________________ ( 1/e1 + 1/e2 - 1) ( 1/.9 + 1/.93 - 1) = .84 R = (.84)(36.58072 x 10 -12 )( ( T1
)4 - ( T2 )4 ) = 16.27 Solve the equation for the source temperature.
