1. Water at 800?C, 15 MPa is flowing through a heat exchanger giving off energy to come out as saturated liquid water at 15 MPa in a steady-flow process. Find the specific heat transfer and the specific flow exergy the water has delivered.
2. A rock bed consists of 6000 kg granite and is at 70?C. A small house with a lumped mass of 12 000 kg wood and 1000 kg iron is at 15?C. They are now brought to a uniform final temperature with no external heat transfer by connecting the house and the rock bed through some heat engines. If the process is reversible, find the final temperature and the work done in the process.
Write a User Defined Function named SimpleCharacter that takes the character inputs either "Coffee" or "Tea" and returns the outputs High Octane for an input of "Coffee" and Low Octane for an input of "Tea".
For your design, compute the coefficient of friction, the friction torque, and the power dissipated as the result of friction.
A CFL bulb that puts out as much light as a 60-W incandescent bulb might costs $10, compared to about $1 for the incandescent bulb. But CFL bulbs are expected to last (on average) 15,00 hours, compared to about 1000 hours for an incandescent bulb.
Explain the relationship between check structure and turnout/outlet structure in terms of their operations/functions
The sports car has a mass of 2.3 Mg and accelerates. at 6m=s2, starting from rest. If the drag resistance on the car. due to the wind is F D = (10v) N, where v is the velocity in m/s,
Assuming that the soil layers continue much beyond 60 feet in a similar pattern (obviously no landfill) in terms of friction and bearing capacities, recommend two different solutions that could allow the shafts to transmit their loads by 1) end be..
A balloon is being inflated at the rate of 15m^3/min. At what rate is the diameter increasing after 5 min? Assume that the diameter is zero at time zero.
Hydraulic cylinders with a stroke of 72 inches are available with bore sizes from 2 o 8 inches. Hydraulic piston pumps with an operating pressure range from 200 to 3000 psig are available with pumping capacities of 5, 10, and 15 gallons per minute..
If we compare brass and bronze having 90% copper, brass (alloy with zinc) will have less yield strength than bronze (alloy with tin). Why?
Knowing that the magnitude of P is 35 N, determine by trigonometry (a) the required angle a if the resultant R of the two forces applied to the support is to be horizontal, (b) the corresponding magnitude of R.
Determine if the bridge would fail under a given load. The truck has two axles and the graph should should begin with 1 axle 7 ft into bridge with the other just reaching the bridge.
A hydrologic structure (e.g. a dam or a dike) is said to be designed for the N-year flood if it has a capacity which will be exceeded only by a flood equal oto or greater than N-year flood.
