- If a kitchen sink has a volume of 20 L. Water flows in the sink with a mass flow rate of 0.5 kg/s. If the drain is closed, how long, in seconds, does it take for the sink to fill up? Density of water = 1000 kg/m3A fluid flows through a pipe with cross-sectional area 0.47 m2 at a speed of 3.8 m/s. What is the volume flow rate of the fluid in the unit of m3/s?A water barometer is used to measure air pressure in a duct where the air is being forced to ventilate a building. One end of the barometer is open to the atmosphere, and the other end is open to the inside of the ductwork. When the tube is bent in the shape of a U, the technician notes that the water level on the side toward the duct is lower than the side toward the atmosphere by 13.4 cm. What is the pressure difference in N/m2? The density of water is 1 gm/cm3 or 1000 kg/m3. Use 9.8 m/s2 for the acceleration of gravity.
