IS required to maintain a loading of 5 kW in a heating unit. At an initial temperature of 15 C°, a voltage of 200 V is necessary for this purpose. When the unit is settled down to a steady temperature, a voltage of 220 V is required to maintain the same oading. Estimate the final temperature of the heating element, if the resistance emperature coefficient of the heating element is 0.0006 ner C° at 0 C

Question
HW. 1.1: it is required to maintain a loading of 5 kW in a heating unit. At an initial temperature of 15 Cº, a voltage of 200 V is necessary for this purpose. When the unit is settled down to a steady temperature, a voltage of 220 V is required to maintain the same loading. Estimate the final temperature of the heating element, if the resistance temperature coefficient of the heating element is 0.0006 per C° at 0 C°. Answer: t2 = 368.15 C°
