considerations. If the loss of pressure be limited to 5 per cent, in order 
to obtain good regulation, the power obtainable at the same efficiency would 
be 110 b.h.p. 
Another instance simpler than the preceding may be quoted for an 
example. The pipe in this case is a single one, 5 in. in diameter and 
2,400 ft. long. The static head 270 ft. Taking C = 60, as before, and with 
a loss of head of 90 ft., equivalent to one-third the static head, the velocity 
is found to be 3-75 ft. per second and the flow 0-51 cusecs. The maximum 
power obtainable at an efficiency of 60 per cent, is found to be 6-24 b.h.p. 
If the loss of pressure be limited to 5 per «cent. the power obtainable at the 
same efficiency would be 3J b.h.p. 
INDUSTRIAL SCIENTIFIC RESEARCH. 
A new and important departure in the organization of industrial research 
schemes has been made in the refractory and pottery trade in Great Britain. 
The scheme was fathered by the Ceramic Society, and the co-operation of 
the Scientific and Industrial Kesearch Department has been secured. The 
following extract from Engineering (London) indicates the nature and 
scope of the organization, and New-Zealanders will be interested to learn 
that Dr. Mellor is so honourably associated with the new venture :— 
“ The British Refractories Research Association can now be registered 
and start working, the report of the committee having been adopted by the 
Ceramic Society. It must be remembered that it is not a trading society. 
Members will be firms and companies, as well as individuals, who are 
interested in refractory materials and products in any way, and the 
association is to be managed by a council elected annually by the members, 
on a very wide basis. Dr. J. W. Mellor, of Stoke-on-Trent, is to be the 
technical director of the research work, and Mr. R. C. Rann has been 
appointed secretary, the offices being in London. Members are to contribute 
annually 5 to 50 guineas for five years, and their only other liability is £5 
per member towards liquidation in case of winding up during the period of 
membership or within one year afterwards. The Scientific and Industrial 
Research Department will contribute for five years an amount equal to that 
contributed by the members. The total sum required is estimated to be 
about £6,000 per annum, but if more should be available it will simply 
mean that more research work can be proceeded with accordingly. Co-opera¬ 
tion with similar research associations in other industries will be aimed at. 
Members will have the valuable privileges of getting answers to technical 
questions, of recommending subjects for research, and the right to use 
any patents or secret processes resulting from the research work of the 
association. It may be added that over 500 guineas per annum for five 
years have already been promised. A preliminary programme of research 
work has been formulated, and it is proposed to have refractories made to 
the association’s specifications, and to have them tested under service 
conditions.” 
Technical and commercial men will realize that this is a practical and 
promising step, and that the future progress and success of the schemes 
should be watched carefully by all those who appreciate the importance of 
fostering the rapprochement between science and industry that is a feature 
of trade activity to-day
