An inclined manometer is used to measure the pressure drop between two taps on a pipe carrying water, as shown in Fig. 4-P13. The manometer fluid is an oil with SG = 0.92, and the manometer reading (L) is 8 in. The manometer reservoir is 4 in. in diameter, the tubing is 1 4 in. in diameter, and the manometer tube is inclined at an angle of 308 to the horizontal. The pipe is inclined at 208 to the horizontal, and the pressure taps are 40 in. apart.

(a) What is the pressure difference between the two pipe taps that would be indicated by the difference in readings of two pressure gages attached to the taps, in (1) psi, (2) Pa, and (3) in. H2O?

(b) Which way is the water flowing?

(c) What would the manometer reading be if the valve were closed?
