A disc \( 30 \mathrm{~cm} \) in diameter and \( 10 \mathrm{~cm} \) thick, initially at uniform temperature of \( 265 \backslash \mathrm{deg} C \) is immersed inliquid at \( -15 \backslash \operatorname{deg} C \). The convective heat - transfer coefficients on ends and on side are 340 and \( 1420 \mathrm{~W} / \mathrm{m} \) ? . K, respectively. Determine (a) temperature at centre of disc, (b) temperature on surface atcentre of one end, (c) temperature at \( 4 \mathrm{~cm} \) away from one of its flat faces and at radius \( 10 \mathrm{~cm} \), and (d)heat transfer rate, after 5 mins? \( \mathrm{p}=7854 \mathrm{~kg} / \mathrm{m} \backslash \mathrm{deg}, \mathrm{Cp} \) \( =487 \mathrm{~J} / \mathrm{kg} \cdot \mathrm{K}, \mathrm{a}=14.82 \backslash \) times \( 10-6 \mathrm{~m} ? / \mathrm{s} \)
