1. T (x) = a + bx + cx2 in a place with a thickness in a place with L = 0.3m inside thickness. In this equation T is the temperature units of Celsius and x meters are given as a = 200 ° C, b = -200 ° C / m, c = 30 ° C / m2. Thermal conductivity of the wall coefficient k = 1 W / m. K. a) The kiosk is outside, losing heat to the outside and outside, bedroom stored calculation. b) What is the heat transfer coefficient when the branch of the wall comes into contact with a fluid having a temperature of 100 ° C at x = L?
