A metal bar of length 20 cm has an initial temperature distribution of 2x+2 °C. Suddenly the right end of the bar is contacted with an environment with constant temperature of 90°C. The left end is brought into contact with a temperature varying environment as 12+0.05t °C, where time is measured in seconds. Find the temperature distribution after 20 seconds.
Answers
ANSWER
0 Given data = 200m length Initial Temperature distribution - 2x+°c Constant Lemperature t=909c. Temperature varying environment = 19 +0.5°C Now the total temperature, T=2x+2+90+12+0.5t T= 2x+10440.5t. regie t=20 sec T=2x +4+0:5(20) T= 2x+104 +10 T= 2x tillt It is temperatene distribution
