Water is pumped between two large open reservoirs through 1.5 km of smooth pipe. The water surfaces in the two reservoirs are at the same elevation. When the pump adds 20 kW to the water, the flowrate is 1 m0. /s. If minor losses are negligible, determine the pipe diameter.
One such example is the stirring of tea leaves in a teacup. Obtain information about "Einstein's tea leaves" and investigate some of the complex fluid motions interacting with the leaves. Summarize your findings in a brief report.
a hydraulic motor has a displacement of 130 cm3 and operates with a pressure of 105 bars and a speed of 2000 rpm. if
Four pounds of air is compressed in a cylinder-piston arrangement while the temperature remains constant at 70°F. If the initial pressure is 30 psi absolute, calculate the work needed to compress the air such that the absolute pressure doubles. Al..
An moles of an ideal gas A and (1-n) moles of an ideal gas B, each at 1 atm, are mixed at total constant pressure. What ratio of A to B in the mixture maximizes the decrease in the Gibbs free energy of the system? If decreases in the Gibbs free energ..
Determines if the member forces are in tension or compression (note that a negative number denotes compression and a position number denotes tension)
consider a compressor operating at steady state. how would you compare the volume flow rate of the air at the inlet and
the rear window of an automobile is defogged by passing warm air over its inner surface. if the warm air is at 30 c and
A brass rod is stress-free at room temperature (20 degrees Celsius). It is then heated up but prevented from lengthening at its ends by external forces. At what temperature does the stress in the rod reach 172 MPa? Assume the modulus of elasticity is..
Determine the uncertainty in the determination of the two specified temperatures. State the relative influence of instrument uncertainty and surface emissivity uncertainty.
