Q1.
(a) changes are negligible? How is it different from a closed stationary system? 8 Explain various methods to increase the power output of the IC engines with
(b) 8 same volumetric capacity. The inner and outer surfaces of a spherical container are maintained at |c| temperatures of T1 = 200 °C and T2 = 80 °C, respectively. The container is having the following dimensions : Inner radius = 8 \text cm, outer radius = 10 \text cm The thermal conductivity of the container material is 45 W/m-K. Obtain a general relation for the temperature distribution inside the container under steady conditions and also, determine the rate of heat loss from the container. 8 A Carnot refrigerator has working temperatures of -30 °C and 35 °C. If it
