CHAPTER 2.0 ANSWER
1 CHAPTER ANSWER 1. A tank is filled with seawater to a depth of 12 ft. If the specific gravity of seawater is and the atmospheric pressure at this location is psi, the absolute pressure (psi) at the bottom of the tank is most nearly Hint: Absolute pressure = gage pressure + atmospheric pressure where, gage pressure = zh and z = specific weight of seawater = SG x w Solution: z = ( lb/cu ft) = lb/cu ft Gage pressure at the bottom of the tank = (12 ft) x ( lb/cu ft) = lb/sq ft = ( lb/sq ft)/(144 sq in/sq ft)= psi Absolute pressure = psi + psi= psi Therefore, the key is (B). open tank contains brine to a depth of 2 m and a 3-m layer of oil on top of the brine.
A clean glass tube is to be selected in the design of a manometer to measure the pressure of kerosene. Specific gravity of kerosene = 0.82 and surface tension of kerosene = 0.025 N/m. If the capillary rise is to be limited to 1 mm, the smallest diameter (cm) of the . 5 glass tube should be most nearly A. 1.25
