A fan is to produce a constant air speed of 40 m/s throughout the pipe loop shown in Fig. P8.88. The 3-m-diameter pipes are smooth, and each of the four 90° elbows has a loss coefficient of 0.30. Determine the power that the fan adds to the air.
Knowing that crank AB has a constant angular velocity of 160 rpm counterclockwise, determine the angular velocity of rod BD and the velocity of collar D when a. delta=0, b. delta = 90.
Calculate the frequency that the instrument will indicate when L = 10 cm ± 0.5 mm. Also, calculate the uncertainty in the measurement in this length.
Superimpose a uniform ?ow parallel to the x-axis of 10 m=s and a source at the origin of strength q ¼ 10p m2/s. (a) Write the velocity potential f and stream function c.
The maximum thickness, h, of a square of material that can be supported is assumed to be a function of the length of the side of the square, , the density of the material, ρ, the acceleration of gravity, g, and the surface tension of the liquid, σ..
The uniform 62-kg pole of 150-mm diameter is hinged at A, and its lower end is immersed in fresh water. Determine the tension T in the vertical cable required to maintain C at a depth of 1 m.
The product cannot resemble any existing product unless it has a valuable new feature, significantly reduces cost, or provides some other meaningful advantage. The final report will include schematics, circuit diagrams, a parts list, and a suggest..
determine the stiffness of the suspension if the amplitude of vibration transmitted to the system is to be less than 15 percent of the floor vibration over the given frequency range.
Odd-parity systems set the parity bit to 1 when the number of 1s in the transmitted data is even. Assume that a parity bit is transmitted for every nibble of data. Design a logic circuit that checks the nibble of data and transmits the proper pari..
Many companies post their financial statements and auditor's report on their home pages, generally under a heading labeled "investor relations." Use one of the Internet search engines to do the following: a. Visit Intel's (www.intel.com) and Micro..
Determine the maximum volume flow rate for which flow in the tubing will remain laminar. Estimate the water level in the tank below which flow will be laminar
Water drips at the rate of 5 drops per second from a leaking tap. Determine the vertical distance between two consecutive drops after the lower drop has attained a velocity of 3 m/s.
A steam turbine is operating at a steady state with a mass flow rate of 3682 kg/h at the inlet. The power output of the turbine is 8700 kW. Steam enters the turbine at a pressure of 40 bar, temperature of 320 oC, and with a velocity of 13 m/s. The ex..
