The U.S. Environmental Protection Agency (EPA) recommends that 222Rn levels not exceed 4 pCi per liter of air (1Ci=3.7x10^10 decay events per second; 1 pCi =1x10^-12 Ci). Convert 4.0 pCi per liter of air into concentrations units of 222Rn atoms per liter of air and moles of 222Rn per liter of air. Write out every step in your conversion and explain your answer.
The line is commercial steel pipe, 25 mm internal diameter, length 120 m. The properties of the fluid are: viscosity 0.99 mNm-2 s, density 998 kg/m3. Calculate the total pressure drop due to friction when the flow rate is 3500 kg/h
You have a heat pump that takes in 256 kW of heat and puts out 604 kW of heat. What is the coefficient of performance (C.O.P.) of the system ( express this value as a fraction)?
In the Deacon process for the manufacture of chlorine, HC1 and O2 react to form Cl2 and H20. Sufficient air (21 mole% 02, 79% N2) is fed to provide 35% excess oxygen and the fractional conversion of HCI is 85%.
How much transmit power is required (disregarding power losses at transmitter and receiver ends) for a maximum BER of 10-5, when using:a. Coherently detected BPSKb. By how much must transmit power be increased to maintain the maximum BER of 10-5 if t..
The adipic acid plant described in Examples 9.5 and 9.9 is to be built in China, with a location factor of 0.85. The cost estimate needs to be updated from 2006 to 2012. Up to 45% of the total investment can be secured as a low-cost loan at an int..
The product is neutralized and washed with water to remove salts. The washed product is usually separated by batch distillation, in which unreacted feeds are recovered first, followed by product, and a polymeric waste is left as residue. The batch..
Miscellaneous friction losses due to the tanker outlet constriction and the pipe fittings in the inlet piping are equivalent to 1000 equivalent pipe diameters. The vapor pressure of chlorine at the maximum temperature reached at the pump is 685 kN..
Evaluate particle diameter at different terminal gas velocities
Large blooms of algae result from high nutrient loading in rivers and lakes, for example, as a result of runoff of fertilizers from agricultural fields.
Select any process/chemical engineering topic of your interest and in about 1000 words explain how modeling is involved in its study and development. regards Mohammed
Propose a model which will show how temperature in the tank changes with time. State assumption used. Solve this model to obtain T(t) given that T(t=200s) = 50°C.
the path followed by a fixed amount of a perfect gas during a reversible process is described by the following
