For a given hypothetical flow, the velocity from time t=0 to t=5s was u=3m/s, v=3m/s. then from time t=5s to t=10s, the velocity was u=2m/s, v=2m/s. A dye streak was started at a point in the flow field at time t=0, and the path of a particle in the fluid was also traced from that same point starting at the same time. Draw the streakline, pathline of the particle, and streamlines at time t=10s.
Assuming the kinetic and potential energy effects to be negligible, determine D) the isentropic turbine efficiency E) the entropy at the exit of the turbine, in kJ/kg K F) the rate of entropy production within the turbine
shaped nozzle such that the velocity along the center line of the flow increased from 1.5 m / s to 15 m / s at a distance of 37.5 m. specify the amount of convective acceleration at the beginning and end of the range.
Collars A and B are connected by a 25 in long wire and can slide freely on frictionless rods. If a 60 lb force Q is applied to B. determine tension in wire when (black) x = 9 in and b) corresponding mag of force P required to maintain equilibrium ..
Titan, a moon of Saturn, is believed by astronomers to have an atmosphere that is about 95% nitrogen. At Titan's surface the acceleration due to gravity is 1.35 m/s2, the atmospheric pressure is 210 kPa, and the temperature is 94 K.
Calculate the area of the reinforcement required( As) in a singly reinforced rectangular beam required to carry an ultimate factored bending moment ( Mu = 140 Kip-ft). Use( f'c=3,000 psi) and( fy=40,000 psi).
An airport runway has a capacity of 60 operations (ie landing and take-offs) per hour. In a particular hour, there are 30 landings evenly spaced over the hour. During that same hour, 20 departing aircraft uniformly arrive at the runway within a 20..
Use microsoft excel functions to find the net present worth of the project, and the internal rate of return,and the annual worth of the project?
A satellite would have a mass of 200 kg on the surface of the moon. Determine the weight of the satellite in pounds when it is in orbit 10,000 mi. above the surface of the earth.
Place the scientific mass on the inclined plane and string over the pulley. Using a force-measuring device, pull the string and determine the force needed to obtain static equilibrium.
