Q1. A power-shift crawler tractor is excavating hard materials of earth (clay) and pushing it a distance of 100 ft. The hourly cost of a power-shift crawler tractor is $200. Maximum reverse speeds are: first range, 6 mph; second range, 9 mph; and third range, 11 mph. Rated blade capacity is 18 LCY. Estimate dozer production if the job efficiency factor is 50 min/hr and what is the expected unit cost for dozer work ($/BCY)?

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?

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.
Steps: 1. Collect Data: Review the Technical Specifications Document for details like storage room dimensions, wall thickness, and materials. Use the ASHRAE CLIMATIC DESIGN CONDITIONS to collect local data. 2. Calculate Room Surface Area: Determine the total surface area of the storage room, accounting for walls and ceiling. Assume that the floor is well insulated and that heat transfer within the floor is negligible. 3. Assess Insulation: Evaluate the insulation thickness and material properties. 4. Calculate Heat and Ventilation Loads: In general, heat load calculations consist of several components such as equipment and internal and external sources. In this project, it is crucial to consider lighting as part of the heat load, in addition to the ventilation load. The other factors can also be taken into account, however, those are optional considerations. For lighting load, see Appendix A. 5. Determine Heat Transfer Coefficients: The convection heat transfer coefficients for…
Q1. Well water contained in an AISI 304 SS pipe network for chemical treatment and posterior distribution by aerial water pipes to different locations in a food manufacturing facility was analysed. The AISI 304 SS pipe network had an approximate 300 m length, 154 mm diameter and 2.0 mm wall thickness. The AISI 304 SS pipes were welded using a Tungsten Inert Gas (TIG) welding procedure. In-situ weld quality assurance was tested by pressurized WW, and no pinhole leakage was detected. After the pipe network remained out of service for 6 months at room temperature containing stagnant, pressurized well water, pitting corrosion was observed on the weld joints and the base material by the presence of multiple pinhole leaks.(a) Discuss, with chemical equations if relevant, TWO corrosion events that may have caused the pitting corrosion.(b) What practical steps could have been taken to mitigate for this potential outcome?(c) Identify corrosion inhibition methods to mitigate for the corrosion…
