An ideal Diesel cycle has a thermal efficiency of 60.7% and a cutoff ratio of 1.8. Using cold-air-standard assumptions, determine the compression ratio r (to the nearest 0.1).

How much power could a wind turbine produce if it had the following specifications? cp = 0.45 -d=1.2kg/m3 d=50m v 5m/s

Apipe of diameter 200 mm (constant) carrying water with an 5 mis and total head is density 1000 kg/m ) with velocity tpward slope. at a certain point, where the elevation is 5 m above a datum,the 21.5 m. a) determine the pressure of the pipe at 5m elevation. determine the pressure at elevation 10m (above same datum) if the of total head at 5m elevation.

The inner surface of a 0.25m thick brick wall of a furnace is kept at 810ºc, when the outside surrounding air is at 22ºc. the convective heat transfer coefficient of the outer surface is 12 w/m2k and the thermal conductivity of the brick is 0.865 w/mk.neglect the convective resistance for the inner side of the furnace and assume that the problem is steady state and thermal radiation is neglected. (a)-sketch the system and calculate the rate of heat loss per unit wall area. (b)-calculate the temperature of the outer wall surface.
