7. Tester. The first gauge was Graduated to read pressures up to 75 lb.per sq. in. This gauge and its connections are shown in Pig. o and willbe referred to hereafter as 2auge G-l. The connections shov.n are ordi-nary 1/4-in. pipe fittings consisting of two nipples (a,a), a tee (b),a drain cock (c), and a cut-off valve (d). The second gauge was grad-uated to read pressures up to 100 lb. per sq. in. This 2auge will bereferred to hereafter as aauge G-5. The connections -were the same asfor gauge 8-1. The average pressure at a section of the stream was obtainedby means of piezometer couplings. A sketch of one of these couplings isshown in Fi^. 6. The pressure of the stream is transmitted to the pres-sure chamber (0) through four 0.10-in. holes A, B, C, D, eaually spacedaround the circumference. A 1/4-in. nipple connected the pressure cham-ber to a small rubber tube leading to the pressure 2auge. A hcod, which is shown in Fig. 7, was set up 6-ft. from thenozzle to deflect the stream into
