Aheat exchanger is used to cool oil from 150°c to 40°c at a rate of 2 kg/s. the oil is cooled using water that enters at 22°c and at a rate of 1.5 kg/s. if the specific heat of the oil is c, = 2.20 kj/kg k and that of water is c 4.18 kj/kg k, determine the outlet temperature of the water in °c

Need only answer if you think you know it

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?
