Defina o coeficiente de transferência de calor por convecção. Explique como o mesmo está relacionado com os mecanismos físicos da convecção. Uma barra quadrada de 2,5 cm de lado, e 15 cm de comprimento é mantida a 260°C. A temperatura do ambiente é 16°C e o coeficiente de transferência de calor por convecção é 15 W/m².°C. Calcule o calor perdido pela barra (taxa de transferência de calor). 
R.: 43,12 W
