That the pressure loss duo to friction in a spraj^ hose of small 

 diameter may amount to several hundred pounds p^r square inch? Yihon 5 gals, 

 per miri, are delivered through a 50- ft, length of s/s in. hose the loss is 

 90 lbs. Delivery of 10 gals, per min, (if that wore possible) v;ould meeai 

 a Iocs of 325 lbs. The same delivery thr'~ugh 50 ft, of rj in. hose results 

 in losses of 18 and 66 lbs. respectively. Strangely enough, v.^aen 20 gals. 

 flow through the stjno length of 3/4 in. hose, the loss is only 40 lbs.
