The contents of a tank are to be mixed with a turbine impeller that has six flat blades. The diameter of the impeller is 3 m and the impeller is installed 1,35 m abobe the bottom of the 2o ft tank. If the temperature is 30 C and the impeller is rotated at 30 r/min, what will be the power consumption ? Find the Reynolds number.
1) Calculate the quantity of pure make up oxygen to be supplied, (in kg/h), in steady state operation.
Determine the flow rate of the refrigerant, the amount of work in the compressors, and the heat loads in all heat exchangers.
The process used in the manufacture of aniline from nitrobenzene is described in Appendix F, Design Problem F.8, which is available in the online material at booksite.Elsevier.com/Towler. The process involves six significant stages:
The coil is placed so that its axis of revolution is perpendicular to a uniform field, as shown in Figure P12.1.10. If the flux per pole is 0.02 Wb, and the coil, consisting of 2 turns, is revolving at 1800 r/min, compute the maximum value of the ..
In Uniformly varying load in simply supported beam, when we are calculating reaction at support we say centorid of triangle will be at 2x/3 from a to b. but, when calculating moment we say centroid will lies at x/3 from a to b, why?
What materials of construction should be specified
what is the optimum operating reaction temperature at a conversion level , xa = 0.8 given- K1 = exp ( 10 -5000/T) K2 = exp ( 40 - 15000 /T) and maximum allowable temperature = T = 300 ok
A condenser is required to condense n-propanol vapour leaving the top of adistillation column. The n-propanol is essentially pure, and is a saturated vapourat a pressure of 2.1 bara.
Assuming that the flux corresponding to a current of 25 A is 40% of that corresponding to a current of 100 A, determine the motor speed at a line current of 25 A at 250 V.
Obtain the output function Y and show that the two circuits are equivalent.
