1. Air at 70°F, Flows into a 10-ft3 reservoir at a velocity of 110 fps. If the reservoir pressure is 14 psig and the reservoir temperature 70°F, find the rate of temperature increase in the reservoir. Assume the incoming air is at reservoir pressure and flows through a 8-in.-diameter pipe.
2. Water flows through a 2-in.-diameter horizontal pipe at a flow rate of 35 gal/min. The heat transfer to the pipe can be neglected, and frictional forces result in a pressure drop of 10 psi. What is the temperature change of the water?
a 1500-kg car enter an s-curve at a with a speed of 96 kmh with brakes applied to reduce the speed to 72 kmh at a
Manually program a lathe to machine a part. The nature and complexity of this part is left to the student however, the design must be approved by the instructor before programming. All design must include convex and concave radii (not tool diamete..
Rhodium (Rh) has an atomic weight of 102.91 g/mol and atomic radius of 1.345 Å. Determine whether it has an FCC or BCC crystal structure, if its density is 12.41 g/cm3. What is its lattice constant? Explain your answers.
The three water-filled tanks shown in Fig. P8.114 are connected by pipes as indicated. If minor losses are neglected, determine the flowrate in each pipe.
the atmosphere is stable with a lapse rate of -0.2 degree c100 m. the surfaces air temperature is 15 degree c. a parcel
At a given instant the topBof the ladder has an accelerationaB= 2 ft>s2 and a velocity of vB= 4 ft>s, both acting downward. Determine the acceleration of the bottomAof the ladder, and the ladder's angular acceleration at this instant
We use this form because fzero solves for roots of the input function. Recall that fzero() is a function function, and that it that it expects that the function argument which you pass it will only accept one argument. This means that fzero(f(x)) is ..
An ideal Otto cycle with Argon as the working fluid has a compression ratio of 6.8. The minimum and maximum temperatures in the cycle are 450 R and 2,260 R. Assuming constant specifc heats,
Recall bugs are the pain points that bother people, e.g., the BZ box Shark Tank video we saw during the lecture. Start from youself, what bothers you in your everyday life. Is your pain point likely shared by other people?
if the tires do not slip on the pavement determine the points on the tire that have a maximum and minimum speed and the
A 1 foot long cylindrical rod with a diameter of 0.25 inch is subjected to a tensile load of 1,500 lbs. Suppose the rod was elongated 0.01 inch under this load, what is the stress and strain created by the load? What is the Young’s Modulus of the mat..
