Northern Tundra Telephone (NIT) has received a contract to install emergency phones along a new 100-mile section of the Snow-Moose Turnpike. Fifty emergency phone systems will be installed about 2 miles apart. The material cost of a unit is $125. NTT will need to run underground communication lines that cost NTT $7500 per mile (including labor) to install. There will also be a one-time cost of $10,000 to network these phones into NTT's current communication system. You are asked to develop a cost estimate of the project from Nit's perspective. If NTT adds a profit margin of .35% to its costs, how much will it cost the state to fund the project?

A 40 KVA 3300/240V.50Hz .1 phase transformer has 660 turns on the primary . determine 1, the number of turns on the secondary , 2, the maximum value of flux in the core
for a laminar flow of a newtonian fluid in a tube of a circular cross section, show that the ratio of mean shear to the wall shear rate is 2/3
A footing 3m X 3m carries a pressure of 500 kN/ m2 at a depth of 1m in a sand substrate. The saturated unit weight of the sand is 20 kN/ m3 and the unit weight above the water table is 18 kN/ m3.
Assuming constant acceleration, determine how long the train blocked the crossing. Dis- regard the width of the crossing.
A U manometer reads 20 cm air as operating fluid and a given manometric fluid. A single branch closed tube reads 35 cm connected to point 1. If P2 = 1.2 ATM calculate the pressure in point 1 and the density of the manometric fluid.
The output takes the form of a series of peaks where each peak corresponds to a component and a peak area (A) is proportional to the moles (n) of the component ( n = kA) in the sample injected in the GC.
the cost and revenue associated with producing a sustainable component are fixed costs = $112,500. Variable costs = $30 / unit. Revenue = $45 / unit. How many units must the company sell each year to breakeven
