(c) The diameter of the piston and qutled,of the paint sprayer in Fig. 1 is 6 cm and 0.5 cm, respectively. The stroke_of thepston is 25 cm and the height difference between the liquid level in the contairfer'and the upper hole of tube is 12 cm. Calculate the minimum velocity of the piston during pumping to initiate atomizing effect if the liquid density is 1200 kg/m³. Take the atmospheric conditions are 20°C and 95 kPa (air density, Patr = 1.13kg/m³), and the liquid reservoir is open to the atmosphere.
*** 32. A double-chambered container contains one mole of helium in one of its 1000 cm³ Pull to volume chambers. The container is well-insulated, and of low specific heat, so that no appre- remove ciable heat is added to the gas during the process we describe. The gas is initially at a tempera- ture of 300 K and a pressure of 1 atmosphere. The partition between the two chambers is then quickly raised, and the gas expands freely to fill the entire container. Whenever a monatomic gas like helium doubles its volume adiabatically like this, the pressure in the gas will drop to 0.315 of what it was before (for reasons that we did not explain in this chapter), so the final 1000 cm3 1000 cm³ pressure of the expanded gas will be 0.315 atmospheres. a) What is the temperature of the gas after the expansion? b) What is the change in the internal energy of the gas? c) How much heat is added to the gas? [Hint: Maybe read the problem again.] d) How much work is done by the gas as it expands? [Hint:…

For stationary applications, mass and volume considerations for a fuel source are much less important than they are for use in transportation. It therefore may be the most reasonable to sacrifice compactness to minimize requirements for expensive advanced technologies. Consider a plan to provide power to a small city with a population of 100,000, using hydrogen fuel cells with an efficiency of 60%. The average net per-capita power consumption is 6 kW of electricity, heat, and power for an electric vehicle. (a) Calculate the volume of hydrogen needed to provide the city's energy for one month if the hydrogen is stored at a (relatively low) pressure of 1 MPa. (b) If the city has a land area of 100 km2, what fraction of this area would need to devoted to hydrogen storage if the storage tanks were vertical cylinders 3 m in diameter and 5 m high and were packed tightly together in a square array?
