P1.4 A gas is contained in a cylinder behind a frictionless piston of diameter 0.1 m and mass 25 kg. When an additional mass M is placed on the piston the gage pressure of the gas becomes 2.0 bar. The local barometric pressure is 775 mm of mercury. (a) Calculate (i) the mass of M and (ii) the absolute pressure of the gas in the cylinder. (b) The piston is held in this position with the aid of a lock on the outside while heat is supplied to the gas until its absolute pressure becomes 4 bar. Calculate the force on the lock in the final equilibrium state. [Answers: (a) (i) 135 kg, (ii) 3.034 bar, (b) 758 N]

A passenger is standing on a scale in an elevator. The building has a height of 500 feet, the passenger has a mass of 80 kg, and the scale has a mass of 7 kg. The scale sits on the floor of the elevator. (It is an Otis elevator, so we will label it as "O" so as not to confuse its forces with those caused by the earth.) You may take g = 10 N/kg. For doing this problem it might be useful to start by drawing free-body diagrams for the passenger and the scale.Consider the vertical forces acting on the passenger and the scale WE→P: The force of the earth pulling down on the passenger (weight). WE→S: The force of the earth pulling down on the scale (weight). NP→S: The force of the passenger pushing down on the scale (normal). NS→P: The force of the scale pushing up on the passenger (normal). NO→S: The force of the elevator pushing up on the scale (normal). NO→P: The force of the elevator pushing up on the passenger (normal) a) While it is accelerating downward, which of the forces in your…

Air is enclosed by a rigid cylinder containing a piston. A pressure gage attached to the cylinder indicates an initial reading of 25 psi. Determine the reading on the gage when the piston has compressed the air to one-third its original volume. Assume the compression process to be isothermal and the local atmospheric pressure to be 14.7 psi. Ans. 104 psig 3. The viscosity of liquids can be measured through the use of a rotating cylinder viscometer of the type illustrated in Fig. P1.3. In this device the outer cylinder is fixed and the inner cylinder is rotated with an angular velocity w. The torque T, required to develop w is measured and the viscosity is calculated from these two measurements. Develop an equation relating u, w, T, e, Ro and Ri. Neglect end effects and assume the velocity distribution in the gap is linear.…
