An open vat in a food processing plant contains 400L of water at 20 degrees C and atmospheric pressure. If the water is heated to 80 degrees C, what will be the percentage change in its volume? If the vat has a diameter of 3m, how much will the water level rise due to this temperature increase? Hint: In this case the volume change is due to change in temperature.
A piston-cylinder device contains helium gas initially at 150 kPa, 20 degrees C, and 0.5 m^3. The helium is now compressed in a polytropic process (PV^n = constant) to 400 kPa and 140 degrees C.
The James Rives flows in from the East at 320 m^3/min and joins the Jackson River flowing at 605 m^3/min just outside the town of Charlotte, NC. The concentration of BOD in the James River is 14 mg/L.
A 200ft tape is hung in catenary. It is supported at the 80ft mark the tension is 20lbf and the weight of the tape is 3 lbf 5 0z. The measured distance is 187.01 what it the distance after adjusting for sag?
Estimate the power in watts that can be produced by the turbine. Hint: In a time interval Dt,the amount of mass that flows through the rotor is Dm=mDt ,and the corresponding amount of kinetic energy in this flow is (Dm*V square/2)
Part of a vertical piping system consists of 8 ft of 4 in diameter, connected to 8 ft of 3 in diameter above, and connected to 8 ft of 2 in diameter above that. Water at 60 F flows up the pipe (no downward flow occurs)
