A100 ft3 /s water jet (density 62.4 lbm/ft3 ) is moving in the positive x-direction with velocity 20 ft/s. the stream hits a stationary splitter, such that half of the flow is diverted upward at 45° and the other half is directed downward at 45°, and both streams have a final speed of 18 ft/s. disregarding gravitational and viscous effects, determine the force required to hold the splitter in place against the water force.

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 ∘c is 31.8 torr.

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
