Hi all, Sorry if this seems trivial but I think I may have managed to confuse myself and could do with some help. I need to specify a tape heater power output for a small rig through which water will be heated to 200C. Having gone through the Q=m*cp*ΔT equation where: m = 0.1658x10-3 kg/s cp = 4186 J/kg K ΔT = 180K I come out with a power requirement of 1.25KW. This seems like an awful lot of power for such a tiny flow of water. Am I getting something wrong here or do I really need a 1.25KW heating element for this? Thanks in advance for any help.
