Ajet of water exiting through a nozzle is deflected by a curved plate at 60°, the velocity of the jet at the outlet of the nozzle is 30 m /s and it comes out at a speed of 25 m /s. if the mass flow leaving the nozzle is 0.8 kg /s. calculate the magnitude and direction of the resultant force on the plate if the plate is fixed

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2

Which of the following components of a pid controlled accumulates the error over time and responds to system error after the error has been accumulated? a)- proportional b)- derivative c)- integral d)- on/off.

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis
