Question
Chapter 10, Problem 10.56P
Interpretation Introduction
Interpretation:
The amount of nickel in grams that must be added to copper is to be calculated to give an alloy of desired properties.
Concept Introduction:
On the temperature-composition graph of an alloy, the curve above which the alloys exist in the liquid phase is the liquidus curve. The temperature at this curve is maximum known as liquidus temperature at which the crystals in the alloy can coexist with its melt in the
Solidus curve is the locus of the temperature on the temperature composition graph of an alloy, beyond which the alloy is completely in solid phase. The temperature at this curve is minimum known as solidus temperature at which the crystals in the alloy can coexist with its melt in the thermodynamic equilibrium.
Amount of each phase in wt% is calculated using lever rule. At a particular temperature and ceramic composition, a tie line is drawn on the phase diagram of the ceramic between the solidus and liquidus curve. Then the portion of the lever opposite to the phase whose amount is to be calculated is considered in the formula used as:
Percentage of a component in an alloy is calculated as:

5.6 A section of highway has the following flow-
density relationship q = 50k - 0.156k2 [with q in veh/h
and k in veh/mi]. What is the capacity of the highway
section, the speed at capacity, and the density when
the highway is at one-quarter of its capacity?
8.20 Two routes connect a suburban area and a city,
with route travel times (in minutes) given by the
expressions t₁ = 6 + 8(x₁/c₁) and t₂ = 10 + 3(x2/c2),
where the x's are expressed in thousands of vehicles
per hour and the c's are the route capacities in
thousands of vehicles per hour. Initially, the
capacities of routes 1 and 2 are 4000 and 2000 veh/h,
respectively. A reconstruction project on route 1
reduces the capacity to 3000 veh/h, but total traffic
demand is unaffected. Observational studies note a
35.28-second increase in average travel time on route
1 and a 68.5% increase in flow on route 2 after
reconstruction begins. User-equilibrium conditions
exist before and during reconstruction. If both routes
are always used, determine equilibrium flows and
travel times before and after reconstruction begins.
