The motor of your "dune buggy" is fueled by a gas line with a
radius of 4.00 
10-3 m and the fuel pump is rated at
5.45 10-2 kg/s. If the density of the gas
you are using is 730 kg/m3, determine the speed at which
gas travels through the fuel line.
Homework Answers
Volume flow rate Q = mass flow rate/density
= 5.45e-2/730 m^3/s
= 0.000074657 m^3/s
speed v = volume flow rate/area = Q/(pi r^2)
= 0.000074657/(pi*4e-3^2)
= 1.485 m/s answer

It is proposed to pump 1500 m3 of a liquid (density 1100 kg m-3) each day through a total head of 10 m (including all losses) by using either a centrifugal pump or a reciprocating pump. The centrifugal pump discharges 2.0 m3 min-1 when driven by an electric motor supplying a power of 5 kW. The reciprocating pump has a discharge rate of 1.75 m3 min-1 when driven by an electric motor supplying 3.5 kw. (a) Calculate the efficiency of...

A water tower is fed from an underground water source (Figure 2). The difference in level is 67 m. The flow of water must be at least 55 m'/h. To provide this flow (55m/h), a pump must be driven at a speed of 690 RPM. It can turn faster, but without exceeding 900 RPM. Its efficiency is 81%. The pump is driven directly, therefore without gearbox, by an asynchronous motor, which itselif is supplied directly by the 400V/50 Hz three-phase...

An electron of mass 9.11 x 10-31 kg has an initial speed of 4.00 x 105 m/s. It travels in a straight line, and its speed increases to 7.60 x 105 m/s in a distance of 4.20 cm. Assume its acceleration is constant. (a) Determine the magnitude of the force exerted on the electron. N (b) Compare this force (F) with the weight of the electron (F), which we ignored. F ܗܝ| ܝ

When a .22-caliber rifle is fired, the expanding gas from the burning gunpowder creates a pressure behind the bullet. This pressure causes the force that pushes the bullet through the barrel. The barrel has a length of 0.61 m and an opening whose radius is 2.8 103 m. A bullet (mass 2.6 103 kg) has a speed of 370 m/s after passing through this barrel. Ignore friction and determine the average pressure of the expanding gas.

Quantitative: In the 1950s liquid hydrogen was considered as a fuel for a new type of aircraft being developed, the SR-71 Blackbird (shown in Figure 1). Figure 1: The SR-71 Blackbird Early research on the project focused on which fuel to use for the Blackbird. Pratt & Whitney had a J-57 engine that was designed for kerosene and being considered for implementation on the Blackbird. The J-57 only took 5 months to convert to running on liquid hydrogen, however tests...
