Problem 1: Steam in a closed system is compressed by reversible isothermal process in a heat bath at 250 °C, starting from an initial pressure of 15 bar. During the process, the steam receives 400 kJ/kg of work. Determine the final state and the amount of heat exchanged with the bath. Problem 2: Steam at 1 bar, 150 °C, is compressed in a closed system by reversible isothermal process to final pressure of 20 bar. Determine the final temperature, amount of work, and the entropy change of the steam and of the heat bath that is used to maintain the process isothermal.
She believes she can extract 1700 kW of work and 220 kW of heat that will be used to boil water at 1 bar. Her process, whose details are yet to be determined, will receive streams A and B as inlet and will have a single outlet stream that will be ..
Wet steam at 200 °C with 80% moisture is heated by removing 600 kJ/kg of heat. Determine the final state (pressure and temperature and quality, if a two-phase system) if cooling is at constant pressure.
A stream of 5.00 wt% oleic acid in cottonseed oil enters an extraction unit at a rate of 100.0 kg/hr. A separate stream of propane enters the unit. Propane is able to dissolve oleic acid but cannot mix with the cottonseed oil. Two streams exit the un..
A recovery of 95% of particles greater than 100 μm is required. The minimum operating temperature will be 10 °C and the maximum 30 °C. Design a hydro cyclone system to handle 1200 liters/min of this slurry.
Write a comprehensive report on your selection of the form of corrosion - Discerption of the corrosion form.
How many kilograms of natural gas are flowing through the pipelines per hour ( use different steps required in material balance calculations).
What is the pressure of the oxygen gas if the vapor pressure for water at 25°C is 23.8 mm Hg?
The specification for a sieve plate column is given below. Make a preliminary mechanical design for the column. Your design should include:
Use the masses given in the following table to calculate the change in energy when 1 mol of 232Pu nuclei and 1 mol of 231Pa nuclei are each formed from their respective number of protons and neutrons.
Develop a series of design graphs that can be used to demonstrate acceptable combinations of tubes dimensions
A fixed-bed reactor is to be designed for a hydrocracking process. The reactor will treat 320,000 lb/hr of vacuum gas oil (specific gravity 0.85) in the presence hydrogen at 650 ºF, 2000 psig, 1.0 weight hourly space velocity (WHSV).
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
