A rectangular straight fin is 4-cm long and has a square cross-section of 5 mm sides. Its efficiency under a specific condition was found to be 93%. How many such fins are needed to be mounted on a 10-cm-by-10-cm surface so that the finned surface has an overall effectiveness of 10? Neglect radiation and assume adiabatic tip conditions.
