| JOHN MARSTON LIMITED, WOLVERHAMPTON. 9th November, 1935. RADIATOR RESEARCH. Preliminary tests comparing performances of certain radiator cores have been completed. SUMMARY. The preliminary tests carried out indicate : 1. that the Marston Mark V and Mark III cores can compete as regards performance per cubic inch with Morris fin and tube cores, whilst they have an advantage in heat dissipation per pound of metal. 2. that the experimental Excelsior cores are equal to the Marston Mark II in performance. 3. that the experimental Mark VI is superior to any other core tested in both heat dissipation per cubic inch of block and per pound of metal. 4. that the Mark II gives the greatest heat dissipation per unit of prime cost and per unit of sales price. The Morris 2 row gives nearly the same heat dissipation per unit of sales price but the heat dissipation per unit of volume is greater. | ||
