Will you please arrange to test 10 P.III oil coolers which we will hand to you, by means of your shock absorber test rig, as you have done previously. These should be as follows:- 5 coolers - 200 lbs/sq.in. down to Zero pressure - repeat till failure and report number of pulsations. 5 " - 100 lbs/sq.in. down to zero pressure - repeat till failure and report number of pulsations. It is important, therefore, we should have these results at the earliest possible moment. Rm{William Robotham - Chief Engineer}/Std. | ||
