A 2.5-cm-diameter horizontal water jet with a speed of = 40 m/s relative to the ground is deflected by a 600 stationary cone whose base diameter is 25 cm. Water velocity along the cone varies linearly from zero at the cone surface to the incoming jet speed of 40 m/s at the free surface.

- A Pitot tube at a height of 3 m, measures wind velocity 5.3 m/s. What is the wind velocity at a height of 50 m? If the center of a 45 m diameter wind turbine is placed at 50 m, what is the maximum power this turbine may produce?arrow_forwardWater flows through the elbow. It exits to the atmosphere at section 2. The inlet and exit pipe diameters are D,=10 cm and D2=3 cm, respectively. At a weight flow rate of 169,9 N/s. The elevation difference between the inlet and outlet sections is 25 cm. Neglecting the weight of water and elbow, estimate the force [N] on the flange bolts at section 1.

(a) Find the force exerted by the jet if the vane moves with a velocity of 5 m/s. (b) Determine the force exerted by the jet if instead of one flat vane, there is a series of vanes so arranged that each vane appears successively before the jet in the same position and always moving with a velocity of 5 m/s. (c) Determine also the efficiency of the system.arrow_forward
- When a person ice skates, the surface of the ice actuallymelts beneath the blades, so that he or she skates on a thinsheet of water between the blade and the ice.( a ) Find an expression for total friction force on the bottomof the blade as a function of skater velocity V , bladelength L , water thickness (between the blade and theice) h , water viscosity μ , and blade width W .( b ) Suppose an ice skater of total mass m is skatingalong at a constant speed of V 0 when she suddenlystands stiff with her skates pointed directly forward,allowing herself to coast to a stop. Neglecting frictiondue to air resistance, how far will she travelbefore she comes to a stop? (Remember, she iscoasting on two skate blades.)

Suppose the design criteria are as follows: The air density as surveyed after 2 year period averaged at 1.225 kg / cubic meter. The sweeping diameter of the rotor blades is 125m, and the anemometer reading in the area amounts to 4.2m/s on a 2 year period of survey. In the design specifications given, if the actual measurement of power via the substation amounts to exactly 530kW and given that the windspeed is off by 0.05m/s, what could have been the error in the measurement of diameter? Your answer must be in 3 decimal places and in correct signs and measurement.

(b) what is the power necessary? (c) Suppose with the 30 degree vertical angle of discharge would this change the force exerted on the blade? what would it be if it changes?
