Apump draws water from a storage tank (water surface elevation = 70 ft) through a 6-inh pipe. the pump is at an elevation of 50 ft and its 4-inch diameter delivery pipe terminates at a 3 inch diameter nozzle at an elevation of 80 ft. head losses amount to 5 v^2/2g in the 6 inch pipe and 12 v^2 /2g in the 4 inch pipe. if the pump develops a head of 80 ft, what is the system discharge?

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

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
