1. A gas turbine burns methane with 150% theoretical air. Assume the air is 25?C, 100 kPa, and has a relative humidity of 80%. How large a fraction of the product mixture water comes from the moist inlet air?
2. In an engine, a mixture of liquid octane and ethanol, mole ratio 9:1, and stoichiometric air are taken in at T0, P0. In the engine, the enthalpy of combustion is used so that 30% goes out as work, 30% goes out as heat loss, and the rest goes out the exhaust. Find the work and heat transfer per kilogram of fuel mixture and also the exhaust temperature.
The mine's operating costs were projected at $900,000 per year including $400,000 of fixed costs and $500,000 of variable costs. Ms. Peru thought these forecasts accurate.
An open rectangular tanks is 3m wide and 4m long. The tank contains water to depth of 2m and oil (SG=0.8) on top of the water to a depth of 1m. Determine the magnitude and location of the resultant force acting on one end of the tank (i.e. 3m high by..
Show or formulate the shear and bending moment expressions for each board, and plot/draw the shear and bending moment diagrams of the boards.
Define the specialization/concentration of your field. Describe the word ACRONYMS and list the acronym for your expected degree. e.g. CONS for Construction Technology.
A new engineer is evaluating whether to use a higher-voltage transmission line. It will cost $250,000 more initially, but it will reduce transmission losses. The optimistic, most likely, and pessimistic projections for annual savings are $20,000, $15..
Roughly what is the maximum Volume of treated wastewater should you put in the bottle if you want to have at least 2.0mg/l of DO at the test (filling the rest of the bottle with the water
A dairy that processes about 250,000 lb of milk daily produces an average of 65,100 gpd of wastewater with a BOD of 1400 mg/L. The principal opearations are bottling milk and maing ice cream with limited produciton of cottage cheese. What is the was..
Achieve a concentration of 0.5%wt of carbon at a depth of 0.2 mm below the surface of the slab of a metal. The initial concentration of carbon in the metal is 0.1wt%. We first do an experiment by applying a concentration of 5%wt of carbon at the surf..
Find the depth and the top width of a v-notch capable of discharging a maximum of .7m^3/s and such that the head shall be 75mm for a discharge of 5.6 liters per second.
What are the three meterials based on the predominant types of bond and what are the predominant types of bond in each category?
a. Calculate the total energy expended in the acceleration. b. Plot a graph of the kinetic energy of the mass against time. c. Plot a graph of the kinetic energy of the mass against distance.
