contd :- -3- In Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}2/LG19.7.27 we shewed the unfortunate state of affairds where μ for joggles is so very low that irreversibility does not count. For parking μ is high so irreversibility does count i.e. make parking difficult and does not help in joggles. Typical Actual Measurements. EFFICIENCY. .720 .940 Parking 55% 65.6% Joggles. 72.5% 72.2% Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
