A rural two-lane road has a two-way ADT of 6915 vehicles per day. Transportation planners forecast that this road will carry 9660 vpd 10 years from now. What will be the road's DHV 10 years from now? Will more lanes be need to be added by that future year? Assume that a rural road has a capacity of 2000 vphpl.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
