Water in a piston/cylinder is at 90?C, 100 kPa, and the piston loading is such that pressure is proportional to volume, P ??CV. Heat is now added until the temperature reaches 200?C. Find the final pressure and also the quality if in the two-phase region.
A 20,000 gal. capacity tank contains 8,000 gals. ofwater/solids mixture at a density of 12 pounds per gal.(ppg). Fresh water (8.34 ppg) is added at a rate of 10 gallons per minute(gpm).
A gas stream with a particulate loading of 20.0g/m^3 is passed through a 70%-efficient cyclone followed by a 95%-efficient ESP. Calculate the overall efficiency of the system.
The uniform steel shaft has two gears attached to it at B and C, two frictionless bearings, and the motor. The motor generates 15kip·in and the gears consume 10kip·in and 5kip·in. Find the diameter of the shaft if the maximum rotation between A an..
In an irrigation system sometimes water must be pumped over long distances. Consider a system that consistes of a 1 m diameter, 2 km long commercial steel pipe, which connects a river to an irrigation canal.
You need to park a car under it so there can be no supports in the middle. Attached to the wall on one side and steel post on the other.
Waste water is dischared into a aquifer. This waste water contains 0.1 ppm atrazine (a common herbicide). The MCL of atrazine is 5 ppb, the density is 1.19 g/ML and the solubility is 50 ppm.
For a ternary system, three components are present; temperature is also a variable. What is the maximum number of phases that may be present for a ternary system, assuming that pressure is held constant
a well is located in a confined aquifer. the transmissivity of the aquifer is 1200 m^2/d and the storativity is 0.0005. the flow rate is 4000 m^3/d. At a distance 75m from the well,
A 6 inch X 4 inch rectangular beam is subjected to a maximum shear force of 1900 lbf. Determine the shear stresses at each of the following points on the beam cross section:
The tower crane is used to hoist the 2-Mg load upward at constant velocity. The 1.5-Mg jib BD , 0.5-Mg jib BC , and 6-Mg counterweight C have centers of mass at G1 , G2 , and G3 , respectively.
During a hot air balloon race one specific balloon, initially at rest, accelerate vertically upward at a constant rate of a=4.5 ft/s^2 when t0=42 s from the ground the surface, which is at an altitude above mean sea level of s0=3750 ft. When the ball..
