A cylindrical tank measuring 0. 75 m in diameter and 1. 2 m high contains a transformer immersed in an oil bath that produces a uniform surface temperature condition. all heat loss may be assumed due to natural convection to surrounding air at 295 k from the top and side walls. the heat dissipation rate from the transformer is constant at 1. 5kw.
required:
write down the total heat transfer rate equation as a function of surface temperature and relevant characteristic dimensionless numbers
