Hs{Lord Ernest Hives - Chair}/CTS.{C. Trot Salt - Carburation}1/KW.22.1.36.

Note.

This test was carried out with the induction pipe on a level plane.
When the induction pipe is tilted to the equivalent angle of a 1 in 5 gradient on the road, the result is as follows :-
Delivery from drain = 11 pts/hr.
Flow into the inlet ports = 7 pts/hr.
This is due of course to the design of the well, but can be cured by the slight alteration shown on Rm.{William Robotham - Chief Engineer}47 attached.

Conclusion.

The tests show that the design of drain tested is adaptable to the induction pipe without further alteration, other than that shown on Rm.{William Robotham - Chief Engineer}47.

Tests are at present being completed for the non-return valve, and details will follow this report.
