The following is an analysis of the heat losses for the Hispano engine. An 'energy diagram' is given showing the heat dis- tribution express as a percentage of the initial fuel energy. | R.P.M. | H.P. | Heat supplied. | Th. eqvt. wk. done. | Friction. | Ht. to jacket water. | |---|---|---|---|---|---| | 500 | 25.6 | 5200 | 1085 | 127 | 1250 | | 1000 | 56.2 | 10600 | 2385 | 445 | 1740 | | 1500 | 87.5 | 15500 | 3710 | 805 | 2235 | | 2000 | 109.0 | 18800 | 4620 | 1186 | 2640 | | 2500 | 114.5 | 20450 | 4850 | 1653 | -- | Heat losses expressed as %age of heat supplied. | R.P.M. | Work done. | Heat to jacket water. | Friction. | |---|---|---|---| | 500 | 21 | 24.1 | 2.45 | | 1000 | 22.5 | 16.4 | 4.2 | | 1500 | 23.9 | 14.4 | 5.2 | | 2000 | 24.6 | 14.0 | 6.3 | | 2500 | 23.7 | -- | 8.1 | Hs {Lord Ernest Hives - Chair} /ACL. | ||
