100 m3/min of a gas mixture containing 1 mol % water and 99 mol % air is cooled at constant pressure of 1 bar from 200 °C to 25 °C. 50 % of the water in the inlet stream is condensed during this process. Calculate the cooling duty of the process (kW)
List out the different biological process involving acids and bases with relevant equations and in adverse conditions how is the pH level maintained in biological systems?
Consider 1 mole of ideal gas at 1 bar and 300 K, which of the following statements is true? The absolute entropy of the system is negative. Helium (m=4 amu) will have a larger entropy than argon (m=40 amu).
task onesummarize at least 4 methods of measuring temperature. only one of these methods may be one that was discussed
A thermocouple enclosed in a 3.2mm stainless steel sheath (e = 0.6) is inserted horizontally into a duct to measure the air temperature inside. The walls of the duct are at 650o C, and the true air temperature is 560o C. What temperature will be in..
Devise a control system for the distillation column described in Chapter 17, Example 17.2. The flow to the column comes from a storage tank. The product, acetone, is sent to storage and the waste to an effluent pond. It is essential that the speci..
The recovery of each main component in each product is to be 98%. For example, 98% of the propane in the feed stream is to appear in the propane-rich product, and 98% of the combined pentanes in the feed stream is to appear in the bottoms product ..
If the gases leave the tower at 6 atm, 25 °C, and are expanded to, say, 1.5 atm, calculate the turbine exit gas temperatures without preheat, and if the gases are preheated to 400 °C with the reactor off-gas. Also, estimate the power recovered fro..
What is the composition by mass percent of the original mixture? Explain in detail how you arrived at this answer, writing down every step to the solution.
Gas oil at 200 °C is to be cooled to 40 °C. The oil flow rate is 22,500 kg/h. Cooling water is available at 30 °C and the temperature rise is to be limited to 20 °C. The pressure drop allowance for each stream is 100 kN/m2 . Design a suitable exch..
