Problem 7 The situation presented below refers to a particular day at an altitude above standard sea level. A piston-cylinder device with a cross-sectional area of 0.01 m² is exposed to a local ambient pressure Patm = 96 kPa. Inside the cylinder there is water vapor and the piston of mass equal 150 kg rests on a base ring support. You are asked to draw a free body diagram for the piston and determine the water vapor pressure, in bar, required to lift the piston. Consider that the acceleration of gravity is 9.81 m/s² and neglect the friction between the piston and the cylinder wall. Hint: focus on the reaction of the base ring support on the piston before and after the instant when the piston is lifted by the water pressure. Base ring support for piston = 96 kPa Water

Steam to drive an old—fashioned steam locomotive is supplied at a constant gauge pressure of 1.75106N/m2 (about 250 psi) to a piston with a 0.200m radius. (a) By calculating PV, find the work done by the steam when the piston moves 0.800 m. Note that this is the net work output, since gauge pressure is used. (b) Now find the amount of work by calculating the force exerted times the distance traveled. Is the answer the same as in part (a)?

Integrated ConceptsIf you want to cook in water at 150ºC , you need a pressure cooker that can withstand the necessary pressure.

A siphon is used to drain water from a tank as illustrated as shown. Assume steady flow without friction. (a) If h = 1.00 m, find the speed of outflow at the end of the siphon. (b) What If? What is the limitation on the height of the top of the siphon above the end of the siphon? Note: For the flow of the liquid to be continuous, its pressure must not drop below its vapor pressure. Assume the water is at 20.0°C, at which the vapor pressure is 2.3 kPa.
