Steam enters a converging nozzle at 800 kPa and 280C with negligible velocity. If the process is isentropic, estimate the minimum pressure that can be reached in such a nozzle and the cross-sectional area at the nozzle throat at this pressure for a flow rate of 0.75 kg/s.

What precautions should you take to prevent injuries when dealing with heavy loads?

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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
