1. The V-shaped tank has width w into the paper and is filled from the inlet pipe at volume flow Q. Derive expressions for (a) the rate of change dh/dt and (b) the time required for the surface to rise from h 1 to h 2 . ...
A dam discharge into a channel of constant width as shown. It is observed that a region of still water backs up behind the jet to a height H. The velocity and height of the flow in the channel are given as v and h, respe ...
A domestic food freezer maintains a temperature of - 15°C. The ambient air temperature is 30°C. If heat leaks into the freezer at the continuous rate of 1.75 kJ/s what is the least power necessary to pump this heat out c ...
1. According to the equipartition principle, what is the overall energy in J of one mole of water at 1000 K if translational, rotational, and vibrational degrees of freedom are considered? 2. How many equipartition degre ...
The probability of a linear molecule being in a particular rotational level J depends on the temperature, and for J 7 0 there is a temperature Tmax at which the probability for that level reaches a maximum. Derive an exp ...
The wrong size bolts were used to connect the flanges in Problem 5.8, and when the torque is applied to flange B it rotates by 2 degrees (twisting shaft AB) before engaging flange C. Once flange C is engaged both B and C ...
Hypochlorite ion, used as the chlorinating agent in swimming pools, can decompose exothermically, in rare occasions even causing ires. he principal decomposition mechanism is believed to be a. Find the steady-state conce ...
What is the difference between initial and residual preload? Typically, what percentage of the work we do with a torque wrench ends up as preload in an individual bolt? Is the preload mentioned above initial or residual ...
Use Castigliano's second theorem to determine the tip deflection of this cantilever with a length L, a constant E I, and a linearly increasing load with a maximum force/length q0. Confirm your result using Table 9.1.
Given the result of Problem 6.7, estimate the magnitude of the radial deflection of a pressurized cylinder as a fraction of its thickness Problem 6.7: Given that the hoop strain is likely to be a very small number, estim ...
