Two 25-cm diameter horizontal parallel pipes separated by a vertical distance of 8 m, are connected by a u-shaped bend of the same size. water enters the lower end of the bend at the rate of 88.2 kg/s with a pressure of 92.4 kpa. determine the pressure and velocity at the upper end of the bend. if losses are neglected.

Modern high speed trains do not have perpendicular expansion gaps where rails are joined end-to-end any more they are mostly welded together but what might happen if there was a spell of particularly hot weather that causes inspection of the tracks?

A12 mm diameter shaft runs in a plain cylindrical bush 30 mm long that is located in an 18 mm diameter hole in a housing. the shaft-inner bush fit is h8 f and the outer bush-housing fit is h7-p6. make a fully cimensioned sketch of the bush with tolerances. find the maximum and minimum clearance or interference for both fits on the inner and outer diameters of the bush
