Experimental Investigation In Developing Low Cost Concrete From Paper Industry Waste Posted in Project Reports‚ Research Papers | Email This Post ABSTRACT Over 300 million tones of industrial wastes are being produced per annum by chemical and agricultural process in India. These materials pose problems of disposal and health hazards. The wastes like phosphogypsum‚ fluorogypsum and red mud contain obnoxious impurities which adversely affect the strength and other properties of building materials

Find the work necessary to decrease the volume to 5 m3‚ (a) at a constant pressure and (b) at constant temperature. (c) What is the temperature at the end of the process in (a)? (d) What is the pressure at the end of process in (b)? (e) Show both processes in the p-V plane. Problem 2: The temperature of an ideal gas at an initial pressure p1 and volume V1 is increased at constant volume until the pressure

The heat removal comes from the air conditioners which remove 5 kW each. Thus for the net Q to be zero we must have N air conditioners such that (5 kW)N = 9.167 kW. To satisfy this requirement‚ we must have two air conditioning units. 2 A 0.5 m3 rigid tank contains regrigerant-134a initially at 160 kPa and 40% quality. Heat is now transferred to the refrigerant until the pressure reaches 700 kPa. Determine (a) the mass of

CHAPTER 6 MECHANICAL-PHYSICAL SEPARATION PROCESSES Introduction Separation Processes Many chemical processes materials and biological substances occur as mixtures of different components in the gas‚ liquid‚ or solid phase. In order to separate or remove one or more of the component from its original mixture‚ it must be contacted with another phase. The two-phase pair can be gas-liquid‚ gas-solid‚ liquid‚ or liquid-solid. Absorption When the two contacting phases are a gas and a liquid

Concentration derived dimension and is usually expressed gravimetrically as the mass of a material A in a unit volume consisting of a material A and some other materials B. Concentration of A in a mixture of A and B: C_A=M_A/(V_A+V_B ) where CA = concentration of A M¬A = mass of material A VA = volume of material A V¬B = volume of material B Basic unit for concentration is kg/m3 Most widely used
