bliuzodt to mopolb 9. If machine parts are degreased by means of kerosene as shown in the diagram, how much kerosene make-up is needed per day? How much kerosene has to enter the degreasing vat per day? There are about 3 lb of grease per 100 lb of machine parts, and 60 tons of machine parts are processed each day. Five thousand pounds of kerosene (the 10% solution) are carried away by the machine parts each day but drip off and are caught and put back in the degreasing vat. Two hundred pounds of the 10% solution are lost each day from the vat by evaporation, spillage, or by being carried away.
Problem Statement = You install a heat pump to heat a cottage during the winter using the outside air as the heat source. You wish to maintain the interior temperature of the cottage at 22°C. A simplified model of the heat loss through the walls indicates that heat will need to be supplied at a rate of 0.14(Tinterior - Texterior) where Q is the rate at which heat must be supplied to the cottage (in kW), Tinterior is the interior air temperature (in C), and Texterior is the exterior air temperature (in C). You have a 1kW electric motor available to run the heat pump. What is the coldest winter day when the heat pump will be able to keep up to the heating demand?

Problem 2 An Air Force Research Lab engineer is asked to evaluate the maximum theoretical work that could be produced by the first stage turbine section of an experimental jet engine. Test stand measurements provide the following information: a. Entering air conditions: 1400 K, 8 bar b. Exiting air conditions: .8 bar Part 1: Since you don't have a mass flow rate measurement, what will be the units will you report maximum theoretical work in? Part 2: Write the first law equation for your control volume showing all terms. What assumptions will you make to simplify the equation. Part 3: Pin down the outlet state on a notional T-s diagram for air (just show the two isobars). Why did you select this point? Part 4: What assumption about the properties of air will you make in order to solve this problem? Part 5: Use the appropriate form of the 'Tds' equation and the air tables to solve for the exit state. Part 6: Calculate the max theoretical work
Direction: Show your complete solution and box you final answer. Do not round off in between the solutions but round off your final answer to the nearest ten thousandths place(4 decimal places). 1. A fluid enters a machine at 170 m/s, 800 kPa, and with a specific volume of 0.3 m^3/kg. The radiation heat loss is 25 kJ/kg. The internal energy decreases by 495 kJ/kg. If the fluid leaves at 330 m/s, 138 kPa, and 0.95 m^3/kg, determine the work done by the fulid in kJ/kg.

Direction: Graph the heating curve of ethanol using the information given. Check off each item as you add additional information to your graph so that none is missed. Background information of Ethanol: Boiling Point = 78 0C Melting Point = -114 0C Starting Temperature = -120 0C After two minutes, frozen cold ethanol starts to melt. It takes two minutes to melt completely. After eight more minutes, it begins to boil. It boils for six minutes. Heat is added for two more minutes until ethanol reaches 80 0C. Label “melting” where this takes place. Label “vaporization” where this takes place. Label “phase change” where a phase change occurs. Indicate where ethanol is only a SOLID, only a LIQUID, and only a GAS. Of the three phases, label which phase has: weakest IMF, strongest IMF, and medium IMF.
