Example 2.11 Water vapour at 90 kPa and 150°C enters a subsonic diffuserwith a velocity of 150 m/s and leaves the diffuser at 190 kPa with a velocity of 55m/s and during the process 1.5 kJ/kg of heat is lost to the surrounding. Determine:(i) The final temperature4) Oxygen(M=32) expands reversibly in a cylinder behind a piston at constantpressure of 3 bar. The volume initially is 0.01 m3 and finally is 0.03m3 ; theinitial temperature is 170C. Calculate the work done by the Oxygen and theheat flow to or from the cylinder walls during the expansion, cp=0.917kJ/kgK.(6kJ, 21.16kJ)

Only the first question will be answered as per our policy. The problem assumes steady state flow…

16. The rod (0, 1) consists of two homogeneous parts of equal cross- section, touching at the point x = x, and having characteristics a,, k, and a2, kg respectively. Find the steady state temperature in such a rod, if one end of the rod (x = 0) is maintained at zero temperature and the temperature of the other end varies sinusoidally with time. %3D
In a mixing chamber, water at m ̇_1=1 kg/s flow rate, P1= 5 MPa and T1= 100 oC and water vapor at m ̇_2=5 kg/s flow rate, P2= 5 MPa and T2= 500 oC are mixed and Saturated steam is obtained at P3=5 MPa pressure. Calculate the amount of heat transfer (kW) lost from the mixing chamber to the environment at 20 oC.

Inside the wall of a house, an L-shaped section of hot-water pipe consists of three parts: a straight, horizontal piece h = 28.0 cm long, an elbow, and a straight vertical piece e = 112 cm long (figure below). A stud and a second-story floorboard hold the ends of this section of copper pipe stationary. Find the magnitude and direction of the displacement of the pipe elbow when the water flow is turned on, raising the temperature of the pipe from 18.0°C to 42.7°C. (Assume a coordinate system with it's origin at the elbow, the +x-axis to the right in line with the horizontal pipe and the +y-axis going upward.) magnitude mm direction ° (clockwise from the +x-axis)
Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. To get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00oC. Note that this calculation is only approximate because ocean warming is not uniform with depth.
