1. You dive 5 m down in the ocean. What isthe absolute pressure there? Assume your weight is 170pounds.
2.A 2.5 m tall steel cylinder has a cross sectional area of 1.5m2. At the bottom with a height of 0.5 m is liquidwater on top of which is a 1 m high layer of gasoline. Thegasoline surface is exposed to atmospheric air at 101 kPa. What is the highest pressure in the water?
3.Water at 120 celcius with a quality of 25 % has its temperature raised 20 celcius in a constant volume process. What is the new quality and pressure? Draw P-v and T-s diagrams.
4.A pressurized steel bottle is charged with 5 kg of oxygen gas and 7 kg of nitrogen gas. How many kmoles are in the bottle?
5.A laboratory room keeps a vacuum of 0.1 kPa. What net force does that put the door of size 2 m by 1m?
a closed tank contains two straified non misicble fluid layers and compressed air. the fluid of the tank is saline water (relative density 1.036) with a total depth of 3.5m. the top fluid layer is oil (relative density of 08.2) with a depth of 0.6..
Is the system within membrane manufacturer's warranty requirement of maximum flux rate of 14 gfd? What is the annual power cost of the RO system?
A canal was constructed running parallel to a river 1500 ft away. Both fully penetrate a sand aquifer with a hydraulic conductivity of 1.2 ft/d. The area is subject to rainfall of 1.8 ft/y and evaporation of 1.3 ft/y.
An eighteen inch diameter sandstone column is subjected to an axial compressive force of 2x10^6 lb / ft. Find the factor of safety based on the ultimate compressive force. For the ultimate compressive stress of sandstone=85Mpa.
What is the maximum length of trench that can excavated by hand economically rather than by a trenching machine. it cost 900.00 to transport a trenching machine to the job and back to the storage yard
Carbon dioxide at 30 C and 320 kPa absolute pressure expands isothermally to an absolute pressure of 170 kPa. Determine the final density of the gas.
Create a function called [polygon] that draws a polygon in a polar plot. Your function should have a single input paramter - the number of sides.
A 100ft steel tape measure correctly when supported throughout its length under a tension of 1- lb and at a temperature of 72F.It is used on the field at a tension of 18 lb and supported at the two ends only.
The perpendicular distance between two parallel tangents of a reversed curve is 20m. The azimuth of the back tangents of the curve is 270 00 and the azimuth of the common tangent is 310.
vehicle A enters the interstate and travel at 60 mph for 1/2 hour, stops for 30 mins then continues at 70 mph. If a vehicle B enters the interstate at the same location as A,
A 10 m diameter particle of unit density falls through air starting from rest. calculate the time required for the particle to attain 70% of the final terminal speed and the distance traveled by the particle during the time.
A force, 90 N in magnitude, is applied to control rod AB as shown. Knowing that the length of the rod is 225 mm, determine the moment of the force about point B by resolving the force into components along AB and in a direction perpendicular to AB..
