Afour-lane divided multilane highway in rolling terrain has five access points per mile and 11-ft lanes with a 4-ft shoulder on the right side and 2-ft shoulder on the left. the peak-hour factor is 0.84 and the traffic stream consists of 6% trucks, 4% buses and 3% recreational vehicles. the driver population adjustment factor is estimated at 0.90. if the analysis flow rate is 1250 pc/h/ln, what is the peak-hour volume?

(a)976 veh/h

(b)1345 veh/h

(c)1389 veh/h

(d)1779 veh/h

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.
