The no-load cards were taken non-condensing, but the load cardswere taken condensing. This is probably the reason why the friction power shown at no-loadis greater than that at full-load. The efficiency under load condensing isinvariably slightly better than when non-condensing. 618 MANUAL OF MARINE ENGINEERING.
