Example 5 The radial-flow turbine illustrated in Figure 5.15 may be analyzed with the aid of the moment-of-momentum expression. In this device, the fluid (usually water) enters the guide vanes, which impart a tangential velocity and hence angular momentum to the fluid before it enters the revolving runner, which reduces the angular momentum of the fluid while delivering torque to the runner. Figure 5.15 Radial-flow turbine. The control volume to be used is illustrated below in Figure 5.16. The outer boundary of the control volume is at radius rį, and the inner boundary is at r2. The width of the runner is h. -h- U1 Figure 5.16 Radial-flow turbine-runner control volume.

A gas filled in a piston-cylinder arrangement as shown in Figure 1 has a volume of 0.09 m³ at its initial equilibrium state. The gas is slowly heated through the bottom of the cylinder that allowed for the gas to expand at constant-pressure of 2095 kPa to a volume of 1.23 m°. The change in internal energy of the gas is 0.24 kJ. Ignoring the friction between the piston and the cylinder and assuming the atmospheric pressure any value from 90 to 110 kPa, of (a) Calculate the mass of the piston if the area of the piston is 0.047 m2 (b) For the gas as a system, evaluate work and heat transfer, each in kJ (c) For the piston as a system, evaluate work and change in potential energy, each in kJ Piston Gas
