1.a tape is calibrated and found to measure 100.04ft between the 0- and 100-ft marks. what measurements should be laid out to establish a horizontal distance of 682.25ft?
2.list at least three questions you would ask if you were, respectively, a user (purchaser), a client ( manufacturer), or a designer who was about to undertake the design of a portable electric guitar
3.Consider the two-dimensional steady flow where the velocity field is given by V=Vo/L(-xi+yj) . Determine the streamlines for this flow. Plot streamlines for x> or =0
Determine the critical depth in a trapezoidal channel with a 20 foot bottom width and 3:1 (H:V) side slopes if the Q = 1000cfs.
If the amount of heat transfer in the HE unit is 2460 kJ per kg of steam, what is the magnitude of shaft work obtained from the turbine in kW?
A clean glass capillary tube having a diameter of .008 in. was inserted into water with a surface tension of 0.00504 lb/ft. Calculate the height of the capillary rise in the tube.
Two passenger cars are traveling at 65 MPH on a highway moving in the same direction in the same lane. The cars are separated by 25 feet for every 10 MPH of their speed. The coefficient of friction (skidding resistance) between the tires and the r..
A fan blade, initially at rest, rotates with a constant rotational acceleration of 0.9rad/s^2. What is its rotational velocity at the instant it goes through an rotational displacement of 5 radians
Incandescent light bulbs have been phased out in the US because they are very inefficient (i.e., they produce a very large amount of heat). A 10 W light-emitting diode lamp (LED) can produce about the same light output as incandescent light bulbs
A soil sample with specific gravity of solids 2.70 has a mass specific gravity of 1.84 Assuming the soil to be perfectly dry,Determine the void ratio.
Water flows i a 8-m-wide rectangular channel that has longitudinal slope of .0001. The channel has an equivalent sand roughness of 2mm. Calculate the uniform flow depth in the channel when the flow rate is 15m^3/s. Use the Darcey-Weisbach equation..
If a single deposit of $15,000 is invested at 2.75% yearly interest, what equal year-end withdrawls can be made each year for 10 years, leaving nothing in the fund after the 10th withdrawl
At A, the pipe diameter is 24 in and the pressure is 45 psi. At B, the pipe diameter is 12 in and the pressure is 50 psi. Point B is 3 f t lower than A. Find the flow rate if the pump puts 22 hp (16 kW) in to the flow. Neglect head losses.
Compare the head loss for water flow (Q=5 cfs) in a 12 in., 3000 ft. long steel pipe using the darcy-weisbach equation and the hazen-williams formula.
A centrifugal pump is used to pump Vodka (S.G. 0.8) at a rate of 20 gallons per minute to the top of a 30 foot tall tank. The owner wants to use the same pump to pump orange juice (S.G. 1.1). Explain how this change in fluid will affect:
