A chilled-water heat-exchange unit is designed to cool $5 \mathrm{~m}^{3} / \mathrm{s}$ of air at $100 \mathrm{~kPa}$ and $30^{\circ} \mathrm{C}$ to $100 \mathrm{~kPa}$ and $18^{\circ} \mathrm{C}$ by using water at $8^{\circ} \mathrm{C}$. Find the maximum water outlet temperature when the mass flow rate of the water is $2 \mathrm{~kg} / \mathrm{s}$.

Experiments show that in a temperature field, heat flows in the direction of maximum decrease of temperature T. Find this direction in general and at the given point P. Sketch that direction at P as an arrow. T=x²+y²+4z², P:(2, -1, 2)

An absorption air-conditioning system is to remove heat from the conditioned space at $20^{\circ} \mathrm{C}$ at a rate of 90 kJ/s while operating in an environment at $35^{\circ} \mathrm{C}.$ Heat is to be supplied from a geothermal source at $140^{\circ} \mathrm{C}.$ The minimum rate of heat supply is (a) 13 kJ/s (b) 18 kJ/s (c) 30 kJ/s (d) 37 kJ/s (e) 90 kJ/s

In a recent study of the hourly wages of maintenance crew members for major airlines, the mean hourly wage was found to be $20.50, with a standard deviation of$3.50. Assuming the distribution of hourly wages follows the normal probability distribution, if we select a crew member at random, what is the probability the crew member earns between $20.50 and$24.00 per hour?
