Question1
Water moves through a constricted pipe in steady, ideal flow. At one point where the pressure is 2.70 104 Pa, the diameter is 12.00 cm. At another point 0.400 m higher, pressure is equal to 1.30 104 Pa and the diameter is 6.00 cm.
(a) Find speed of flow in the lower section.
(b) Find speed of flow in the upper section.
(c) Find volume flow rate through the pipe.
Question2
A 12.50 kg block of metal measuring 12.0 cm 10.0 cm 10.0 cm is suspended from a scale and immersed in water. The 12.0 cm dimension is perpendicular and the top of the block is 5.10 cm below the surface of the water.
What is the reading of spring scale?
