1) Water flows through a hose and fills a 45 gallon drum in 7 minutes a) what is the volumetric flow rate in m³/sec ? Conversion you need: 1 m² = 264 gallons b) what is the mass flow rate in kg/sec ? c) if the hose has a diameter of 1.25 cm (note the units), what is the velocity of the water as it travels through the hose ? (Use continuity) d) Now you put nozzle on the end of the hose and it makes the outlet opening 1/3 of what it was. Use the Bernoulli equation and determine vz now. Vi is your answer from "C" above

2. A wooden block of mass 20 kg is floating in a pool. This is a fresh water pool, so we can assume a density of 1000kg/m3. What is the volume of water displaced by this wooden block? If the volume of the block is 104 liters, what is the density of the block in kilograms per liter? What is the density of the block in kilograms per cubic meter? What percentage of the block is submerged?
Explain why? i. Nozzles for liquids are always convergent. ii. Convergent nozzles can't be used for supersonic flows. iii. Shockwave appears in convergent- divergent nozzles. iv. Mass flow rate is more in case of supersaturated flows in nozzles. v. Discharge co-efficient is assumed unity in C-D nozzles. vi. Isothermal expansion process is also known as isothermal heating. vii. Heat is a transitory energy. viii. Isentropic index (gamma) is a' greater than unity. w
