Suppose you want to go from Dhaka to Chittagong, then to Cox’s Bazar. You can travel from Dhaka to Chittagong by bus or by train. From Chittagong, you can take a bus to Cox’s Bazar. The ticket price for bus and train are given below – Dhaka to Ctg Bus = 1200/- Dhaka to Ctg Train = 1000/- Ctg to Cox’s Bazar Bus = 250/- Now choose the least expensive method for you to travel by writing a program in C.

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

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

Atmospheric air has a temperature (dry bulb) of 80° f and a wet bulb temperature of 60° f when the barometric pressure is 14.696 psia. determine the specific humidity, grains/lb dry air. a. 11.4 c. 55.8 d. 22.5 b. 44.1
