THE CABLE SHIP ON REPAIRS. 237 



la the case of Type D, therefore, we must add 20 per cent, 

 to the actual volume of the cable to cover waste space In 

 coiling ; that is 



26-8 cubic ft. plus 20% = 32 cubic ft., 



as given in the last column of above table. Therefore the 

 actual amount of cable of this type that can be coiled into a 

 tank 30ft. diameter is 



679 

 -— — =21 nauts per foot height coiled. 



On this basis the approximate lengths of each type of cable 

 that can be coiled into tanks of 18ft., 25ft. and 30ft. diameter 

 are worked out below. The figures are arrived at by dividing 

 in each case the net coiling space per foot height of tank 

 by the actual space reckoned per naut in coiling, for each type 

 of cable as given in the last column of above table. 



Tank, 30ft. diameter. Cone, 6ft. mean diameter. 

 Net coiling space per foot height of tank = 679 cubic ft. 



Type S E 2-4 nauts per foot height coiled.
