| 9/ General summary of the above tests show 1. That the water temperature is unaffected by various means of body ventilation ( dashboard not being filled in and side engine guards being louvred during all the tests ) Generally this is the worst condition for heating up the water, tests at high speed did not cause so great a rise in temperature. 2. The temperature inside the body is reduced considerably and brought to quite normal conditions by causing pressure inside the body by the front windows being open, the floorboard temperature only slightly decreased but not materially, this is more noticeable when the side windows are also closed with the front windows left open. These features also exist under other Cont. 31 | ||
