5. a 5 mhz ultrasonic transducer is used for measuring blood flow in a vessel of 6 mm internal diameter. if the average doppler frequency is 4000 hz and doppler angle is 60o, what is the average flow rate? assume the flow velocities are constant in the vessel and the sound speed in blood is 1540 m/sec.

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.
