A bimetallic strip is to be constructed of yellow brass and Invar for the purpose of measuring temperature over the range from -10?C to 120?C. The length of the strip is 2.5 cm and each sheet has a thickness of 0.3 mm. Assuming that the strip is bonded at 30?C, calculate the deflection at the extremes of the design temperature range.
Air mass of 4 kg of liquid water is cooled from 90c to 10c under a constant pressure. Determine the change in its entropy, assuming the process to be reversible.
Given that that there is no budget to built any type of artificial protection enclosure or retention wall but you still have some allowance for using earthmoving equipment, which of the techniques discussed in class would appropriate in case slope pr..
a piston/cylinder contains liquid water at 2 degrees Celcius, with a freely moving piston maintains a pressure of 200 kPa on the water. Heat transfers to the liquid water until the piston/cylinder contains only saturated vapor.
Compute and tabulate the bearingsof the sides of a regular pentagon (polygon with five equalangles), given the starting direction of sideAB.
Helium gas is compressed isentropically from 1 bar and 25 C to a pressure of 10 bar. The temperature of Helium after the compression is A) 25 C B) 63 C C) 250 C D) 384 C E) 476 C
The telescope of the instrument is 5.25 ft above the ground station, whose elevation is 415.65 ft. What is the elevation of the tip of the spire? (Ignore atmospheric refraction and earth curvature)
A 10 inch steel pipeline 100 feet long carriers 2000 gpm of crude oil. Calculate the head loss when the oil is at a) 80 degree F b) 110 degree F.
Discuss how relative motion is a critical issue in the midair refueling of aircraft. Would control of this process be with the pilot of the tanker or the aircraft being refueled
The exhaust from a rotary kiln hazardous waste incinerator must be cooled from 1200 degrees C to 300 degrees C before entering a spray dryer for acid gas removal.
Water is flowing in a 6-cm diameter pipe at 20 m/s at 10?C. If the pipe enlarges to a diameter of 12-cm, calculate the reduced velocity. Also, calculate the mass flux rate and the flow rate.
Draw the state-transition diagram for a deterministic FSM that recognizes the strings AI(AB). Take care not to accept any other strings, such as ABB.
A condenser is maintained at 60?C by cooling it with atmospheric air coming in at 20?C and leaving at 35?C. The condenser must reject 25 MW from the water to the air. Find the flow rate of air and the second-law efficiency of the heat exchanger.
