A lap joint is formed using two plates which are 15 mm thick, by using resistance welding. Current of 12000 A is passed for 0.1 sec and the effective resistance was found to be 130 μΩ. If the density of plate is 0.0078 g/mm3 and heat required to melt is 1360 J/g, then % of heat distributed to surroundings is _____
(Joint is cylindrical with 5 mm diameter and 4 mm height)Enter numerical value using the virtual keypad. Round off where necessary.
