A plant operation has fixed costs of $2,000,000 per year, and its output capacity is 100,000 electrical appliances per year. The variable cost is $40 per unit, and the product
sells for $90 per unit.
a. Construct the economic breakeven chart.
b. Compare annual profit when the plant is operating at 90% of capacity with
the plant operation at 100% capacity. Assume that the first 90% of capacity
output is sold at $90 per unit and that the remaining 10% of production is sold at
$70 per unit.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

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.

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented
