Problem Statement Consider isentropic supersonic flow around the sharp expansion corner illustrated in Figure shown below: Mi M2 Figure 1. Isentropic supersonic flow around a sharp expansion corner. The relationship between Mach number before the corner (M₁) and after the corner (M₁), derived by Zucrow and Hoffman (1976), is given by o = bâ [tan-t ཊཌི་ཊྛཱི -1」 བཻ _ tan-iཊཌི་ཤྲཱི -1 j -[tan-t{wę - 1)2} - tan-i{of - 1)4}] where b b = (x + 1) and y is the specific heat ratio of the gas. Use Newton-Raphson Method to solve for M₂ for specified values of y, 6, and M₁. For y = 1.4, solve for M₂ given the following combination of M₁ and 6: 1.0 and 10.0°. Correct up to 1.0x105.

Give the Greenberg's speed-density relation equation for the following traffic data.
A freeway traffic stream was observed to have a density of 22.0 veh/mi/ln when the mean speed was 55.0 mi/h. On another occasion at the same location, the jam density was found to be 132 veh/mi/ln. Assume Greenshields' model of traffic flow applies. The optimum speed (in mi/h) is: a) 22.0 b) 33.0 c) 55.0 d) 66.0 e) None of he above
Baras Highway is a Class III Two-lane highway that is considered a level terrain. Based on the data, 983 passenger cars travel on average per hour for both directions with a directional split of 80/20. The traffic stream contains 6% large trucks, 5% buses, and 3% recreational vehicles. Assume PHF = 1.0. Determine the analysis direction flow rate in pc/hr.
