4. A multimeter having a sensitivity of 4,000 2/V is used to measure the
voltage across a circuit having an output resistance of 20k92. The open-
circuit voltage of the circuit is 7.5 V. Find the reading of the multimeter
when it is set to its 10 V scale. Also find the percentage error.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
