1. AU-tube manometer is connected to a closed tank containing air and water is shown. At the closed end of the manometer the air pressure is 16 psja. Determine the reading on the pressure gage for a differential reading of 4 ft on the manometer. Express your answer in psi (gage). Assume standard atmospheric pressure and neglect the weight of the air columns in the manometer.

Figure Q1 (a) shows the tank attached with piezometer tubes. The pressure gauge A is 2.3 kPa. The specific weight for the air is 12.0 N/m', the specific weight for gasoline is 6670 N/m³ and the specific weight for the glycerin is 12360 N/m³.

1- Water flows through a horizontal pipe at a rate of 9.1 L/s. The pipe consists of two sections of diameters 10.16 cm and 5.08 cm with a smooth reducing section. The pressure difference between the two pipe sections is measured by a mercury manometer. Neglecting frictional effects, (a) determine the differential height of mercury between the two pipe sections. (b) How would the reading change if the manometer on the 2in pipe is replaced by a pitot tube? 10.16 5.08 h

(Bernoulli/continuity/Pitot tube) Two Pitot tubes and two static pressure taps are placed in the pipe contraction shown in the figure below. The flowing fluid is water, and viscous effects are negligible. Determine the two manometer readings, h and H. V=1.7 ft/s h = H= 6.4 in. Air ↓ SG= 1.10 ft ft TH 3.8 in.
