Answer / sr

Mass balance is also considered as material balance, but we
can do material balance by considering the molar flow rate
(kmol/hr)of the input and output material. When we do the
material balance considering the mass flow rate ( kg/hr)
then it is called mass balance.

Answer / zeeshan

WHAT EVER IS THE UNIT MOLAR OR KG ,WEIGHT ON EACH SIDE OF
THE EQUATION WILL BE UNDER THE LAW OF CONSERVATION OF MASS

Answer / viral

By the Material balance we know that how much amount of material c0‹2nsume,required,also by-product.while the mass balance we know only the quantity of material for particuler operation.

Answer / bharat

material balance and mass balance are one and the same.both are based on conservation of mass not in volume or moles.

Question 42 - According to Margules Equation, P = x(1) p(1) g(1) + x(2) p(2) g(2) for a two-component mixture where P is bubble pressure, x is mole fraction, p is saturation pressure, g is constant given by ln g(1) = x(2) A x(2). Find the value of A as a constant when P = 1.08 bar, p(1) = 0.82 bar, p(2) = 1.93 bar in a 50 : 50 mole fraction mixture. Estimate the pressure required to completely liquefy the 30 : 70 mixture using the same equation, by proving P = 1.39 bar. Take note that ln g(2) = x(1) A x(1), ln g(1) = x(2) A x(2).

MICROBIOLOGICAL ENGINEERING - QUESTION 28.1 : In the calculation of the growth of bacteria, colony forming unit (CFU) in serial dilution is used. In a laboratory, viable count assay is used to estimate CFU. Formula applied is CFU / mL = (number of colonies x dilution) / (amount plated, in unit mL). Acceptable plate count is either between 20 and 200 or between 30 and 300 according to 2 different references. A wastewater sample of 200 ml is added to and mixed with 1.8 L of sterile water. Another 200 ml of the mixture is added to and mixed with 1.8 L of sterile water. (a) Calculate the dilution of first mixture and the dilution of the second mixture. (b) 100 microlitres of wastewater samples from the first mixture and the second mixture are placed separately on 2 different alga plates. The first plate has 250 colonies and the second plate has 23 colonies. Calculate the average CFU / mL.
