Milk enters a heat exchanger at 158C and at a rate of 2000 kg/h. The heating medium is the latent heat provide by
steam. The outlet temperature of the product is 958C and the
specific heat of the product is 3.9 kJ/(kg 8C). If the latent
heat provided by the steam is 2600 kJ/kg, estimate the flow
rate of steam needed to accomplish product heating.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Fluids at rest possess no flow energy. a)- true b)- false

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
