| R.R. 235a (200 T) (S.D. 408. 26-4-17.) Bm. 2/156/12. EP.{G. Eric Platford - Chief Quality Engineer} from EFC. EFC1/T8.9.17. X.3178 - H.P. CORRECTION FOR ATMOSPHERIC TEMPERATURE AND PRESSURE. Herewith we return your sheet re the above, having taken copies of same. We are preparing a table of corrections according to the results given on this sheet for temperatures from - 5°C to 25°C by steps of 1°C, and for pressures of 28" to 31" of mercury by steps of 1". We will send you a copy of this as soon as it is ready. EFC. | ||
