Using Carnot heat engine principles, determine for a gasoline-burning internal combustion engine with peak combustion temperature 800 K:
a. The maximum theoretical efficiency if the ambient air temperature is 25°C
b. The net amount of work (in W) that we get at this efficiency if gasoline combustion yields 8000W of heat.
c. Assume the engine is on a car and that 50% of the waste heat goes out of the tailpipe while the rest goes to the system cooling the engine. Compute the minimum flow of coolant [L/hour] if you want to keep the coolant below boiling temperature after cooling the engine. Assume that the coolant has the same properties of 10 °C water and that the radiator brings the coolant down to ambient temperature.
A distance is measured through mountainous terrain and found to be 5182.40 ft. If on the average a plumb bob is used every 50 ft with a probable error of ±0.02 ft, what is the probable total error in the whole distance?
If there are 50 vehicles on a 4000-ft highway lane and the average time headway between two adjacent vehicles is 2.2 seconds. A) Calculate traffic density in vehicle/mile (vpm) and average space headway in feet/vehicle (fpv).
Where should ashings be installed in a masonry wall? What is the function of the ß ashing in each of these locations?
Compute the area in acres of a triangular parcel of land whose sides measure 48.78 mm, 84.05 mm, and 69.36 mm on a vertical photograph taken from 6050 ft above average ground with a 152.4 mm focal length camera.
if you had a choice of three kinds of aggregate--a sandstone,a crushed basalt,and a quartizite,you may select the basalt.Give one possible characteristic or property of sanstone and of the quartzite that made you decide not to select it for your c..
You have two wires connected end to end. Wire 1 is copper and wire 2 is made using a special carbon conductor. Wire 1 has a resistance of 0.215 ohms/ft and is 500 ft long. Wire 2 has a resistance of 0.141 ohms/ft and is 700 ft long.
Show that all diagonal members of the truss carry the same force, and find the magnitude of this force.
Identify relevant research areas and any opposing views - what you are going to use in order to fill the gap in the knowledge. What areas are to be combined
A canal cut in rock (n= 0.030 is trapezoidal in section with the bottom width of 6.10m and side slopes of 1 on 1. The allowable average velocity is 0.76 m/s. What slope will produce 5.66 m^3/s
The diameter of the soil column is 8.0 cm, the length of the soil column is 16.0 cm. The hydraulic head loss across the soil specimen is 6.4 cm. Over a period of 3 min, 350 mL of water is collected at the downstream side of the soil specimen.
a job requires excavating and hauling 500 cyds (in situ) of sandy soil. in your posession is an excavator and a dump truck (capacity 30 cyds loose) the dump truck has a round trip travel time of 5 mins and 45 secs to the dump site and back.
