In a venturi nozzle flow, the inlet conditions are p1 = 08 x 103 kPa gauge and d1 = 100 mm and the outlet conditions are p2 = 0 kPa gauge and d2 = 50 mm. Find the flow rate of water. Assume CD = 0.98 for the venturi coefficient. a) (30) Neglect viscous effects (friction loss).
b) (10) Consider viscous effects.

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
