A Carnot heat pump cycle is executed in a steady-flow system with R-134a flowing at a rate of 0.21567 kg/s. The net power input to the cycle is 5 kW and the ratio of the maximum to minimum temperature is 1.2. If the refrigerant changes from saturated vapor to saturated liquid during the heat rejection process, (a) plotT-v diagramof the Carnot cycle process with saturation lines, (b) determine the temperature THduring the cycle process.

At 12 noon, the count in a bacteria culture was 400; at 4: 00 pm the count was 1200 let p(t) denote the bacteria cou population growth law. find: (a) an expression for the bacteria count at any time t (b) the bacteria count at 10 am. (c) the time required for the bacteria count to reach 1800.

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
