You are to design a microfiltration system for the community of Lastnight. The design flow rate is 0.960 m^3/s. The temperature of the water is constant throughout the year at 10. The membrane you have chosen has a maximum TMP of 230 kPa and a resistance coefficient of 3.5 x 10^12 m-1. Based on pilot testing, the operating TMP should be not greater than 75% of the maximum TMP.
a. Determine the required membrane area.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false
