Coal discharged from a dump truck with an initial velocity (v)= 1.8m/s at 50 degrees falls on conveyor belt B. Determine the required velocity v(B) of the belt if the relative velocity with which the coal hits the belt is to be vertical.
The tank cover is airtight, and the pressure above the water surface is 2 atm gage. The system is at sea level. Determine the max height to which the water stream could rise.
A 60 ohm, 40 ohm, and 20 ohm resistor are each connected in parallel across a 120VAC source. What is the total current.
Determine if the shaft has infinite fatigue life. If not, determine the number of cycles to failure. Also determine the safety factor for first cycle yield and draw a free body diagram, shear and moment diagrams, and graph the loads on the shaft..
With reference to basic constructional features, contrast the methods of compression employed by positive displacement and dynamic air compressors.
determine the minimum time needed for the plate temperature to reach 140°C.
Assuming the plant operates on the ideal vapor-compression cycle using refrigerant 134-a between the pressure limits of 120 and 700 kPa, determine
Water is being pumped from a large lake to a reservoir 30 m above at a rate of 5x10-3 m3/s by a 12 kW (shaft) pump. If the irreversible head loss of the piping system is 8m, determine the mechanical efficiency of the pump.
an ideal rankine cycle produces 100 MW of power. If the steam enters the turbine at 100 bar and 500C and is condensed at 1 bar, determine the flow rate of stream and the thermal efficiency.
A tensile specimen of cartridge brass sheet has a cross section of 0.320 in. × 0.120 in. and a gage length of 2.00 in. Calculate the engineering strain that occurred during a test if the distance between gage markings is 2.35 in. after the test.
What is the discharge revised discharge pressure (guage pressure) of the compressor ? Is the assumption of change in temperature valid for calculating the discharge pressure of the compressor ?
A power outage occurred at a water distribution pump station. Before the power outage the station was pumping with one pump at 6,000 gpm in a 18" diameter Steel Pipe
Draw the T-s diagram (hint: it would help to begin with a schematic of the cycle) and.
