A steam turbine operates with 1.6 MPa and 350 deg C steam at its inlet and saturated vapor at 30 deg C at its exit. The mass flow rate of the steam is 22 kg/s, and 610.2 kW of heat is lost through the casing of the turbine. 1. Create a sketch of the problem and indicate the control volume. 2. Write the continuity and energy equations and cross out terms by stating the relevant steady state assumptions. 3. Determine power produced. 4. Determine the specific work.
A stream of methane(CH4, Cp=4R) flowing at 3.0 kmol/min is isobarically heated in a well‑insulated heat exchanger from 30.00 ∘C to 1.50×102 ∘C. The second side of the exchanger is fed with saturated water vapor, which is isobarically cooled to a saturated liquid when it leaves. As unit operator, you have the choice of feeding high‑pressure steam (HPS) at 4.00 MPa or medium pressure steam (MPS) at 1.00 MPa. Assume Tsurr=27 ∘C. Find the mass flow rate of water and lost work if high pressure steam (HPS) is used. Find the mass flow rate of water and lost work if medium pressure steam (MPS) is used. Which is the better choice of steam to use?
A counter-current extractor is employed to extract oil from a solid meal using ethyl ether as the solvent. The fresh meal is charged to the unit at a rate of 1000 kg/h and contains 25.0% (weight) oil. Pure solvent enters the bottom of the extractor. The overflow from the unit contains 60% (weight) oil. The underflow contains 0.25 kg of solution per kg of oil-free solids and the concentration of oil in the underflow is 12%. Calculate the following: a. The amount of solvent b. The percentage oil recovery
