Student Government at a University is chartering a plane for Spring Break. The plane can seat 150 passengers. The airline will charge $120 per passenger and added to this a surcharge of $15 per passenger for each unsold seat. Let x represent the number of unsold seats
(a) Show that the airline s revenue R = (150 - x) (120 + 15x)
(b) How many seats should be unused to maximize the airline s revenue?
(c) What price would each passenger pay if the airline maximized its revenue?
(d) Is this a good deal for the Student Government?
The compressor in a plant receives carbon dioxide at 100 kPa, 280 K at a low velocity. At the compressor exit the carbon dioxide is at 1100 kPa and 500 K with a velocity of 25 m/s. The carbon dioxide then flows into an isobaric heat exchanger where i..
A vibrometer has an undamped natural frequency of 10Hz. and damped natural frequency of 8 Hz. Find the lowest frequency in the range to infinity at which the amplitude can be directly read from the vibrometer with less than 2 percent error.
A plate, 0.001 in distant from a fixed plate, moves at 2 feet per seconds and requires a force of 0.04l bar per feet square to maintain this speed. determine the fluid viscosity of the substance between the plate.
A commercial food waste grinder in which the final shaft rotates at between 40 and 44 rpm is to be designed. The input is from an electric motor running at 850 rpm and delivering 0.50 hp.
100kpa and 22 degc air is contained in a rigid tank of 2 m3. there is supply line connected to the tank through a
We wish to meter the flow with a thin-plate orifice and a differential pressure transducer that reads best at about 55 kPa. What is the proper ratio for the orifice?
carbon dioxide co2 contained in a piston-cylinder arrangement initially at 87 psia and 720 r undergoes an expansion to
We have only a water quench available to us. Design the plate, assuming that we only have the steels given in Figure 13-21 available to us.
Obtain all appropriate differential equations, stressdisplacement relations, and all boundary conditions.
this would provide you with a set of Reynolds numbers. Next, using the integral method, determine the velocity profiles within the boundary layer to be followed by determination of the heat transfer coefficient values for your selected Reynolds numbe..
