Water is to be heated from 20°C to 70°C as it flows through a 40 mm internal Hiameter and 600 mm long tube. The outer surface of the tube is wrapped with electrical wire which acts as an electrical resistance heater. The heater provides uniform heat flux throughout the surface of the tube. The outer surface of the heater is well insulated. At steady state if the system provides hot water at 0.2475 kg/s, determine the power rating of the resistance heater and the inner surface temperature of the pipe at the exit. p= 990 kg/m³: k = 0.631 W/(m K); Cp 4180 J/(kg K); v = 0.66 x 10-6 m²/s; Pr-4.328

Water is to be heated from 20°C to 70°C as it flows through a 40 mm internal diameter and 600 mm long tube. The outer surface of the tube is wrapped with electrical wire which acts as an electrical resistance heater. The heater provides uniform heat flux throughout the surface of the tube. The outer surface of the heater is well insulated. At steady state if the system provides hot water at 0.2475 kg/s, determine the power rating of the resistance heater and the inner surface temperature of the pipe at the exit. 990 kg/m³: k 0.631 W/(m K); C 4180 J/(kg K); v = 0.66 x 10-6 m²/s; P Pr-4.328 =
