A U-tube manometer is connected to a closed tank containing air and water as shown in Figure 2. At the closed end of the manometer the absolute air pressure is 140 kPa . Determine the reading on the pressure gage for a differential reading of \( 1.5-\mathrm{m} \) on the manometer Express your answer in gage pressure value Assume standard atmospheric pressure and neglect the weight of the air columns in the manometer.
