An experimental model is being prepared based on the requirements of a prototype pump that is going to be used in a chemical plant. The prototype should deliver 0.8 m3 /s of benzene with a pressure increase of Δp = 320 kPa. What should the volume flow rate and pressure increase produced by the model be to properly satisfy similarity between prototype and model? The model is one–sixth the size of the prototype. If the model requires a power of P = 900 kW to operate, what would the power requirement of the prototype be? The prototype and the model will be using the same fluid. The functional relation describing this problem is P = f (rho, μ, Q, Δp, l). Select your repeating variables considering the three relevant factors of similitude analysis: Geometry (l), Properties of the material (rho), and external effects (Q).

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
