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?
water flows into a weigh tank for 30 minutes. Calculate the increase in weight of the tank, if the discharge is 1.5 ft^3/s. The temperature is 50 F.
Calculate the primary consolidation settlement for the CH layer, assuming that it is normally consolidated with a water content of 70% and a compression index of 0.25.
The beam is to be hoisted using two chains. Determine the magnitudes of force and acting on each chain in order to develop a resultant force of 500 directed along the positive axis. Set = 41
a circular drain pipe has a radius of 375 mm. it conveys water 30 ordmc from location 1 to location 2 between which
Oil flows through the Trans-Alaska pipeline. Because oil is viscous, you might think that the flow is laminar. (a) What is the minimum flowrate (m3/s) for which the flow would likely be laminar.
The results of his experiment are tabulated below. Assuming the experiment was conducted in a completely-mixed batch reactor, determine the decay rate constant for the die-off of anthrax.
A .2kg mass of argon gas fills a .05m^3 piston-cylinder volume at a pressure of 400 kPa absolute. The piston induced pressure is changed until the volume expands to twice its original value, while the temperature remains constant.
While traveling around the curved path, the motorcyclist increases speed by 1.25ft/s^2 . Part A - Finding the time interval for the motorcyclist to reach a given acceleration If the motorcyclist starts from rest
Shaquille O Neal, who is listed as 7`1" tall is out of the NBA Playoffs and so has time to visit is pool. If he stands vertically in the water, completely submerged
Determine the cycle time for a single engine scraper rated at 21 cy heaped that is used to haul material from a pit to a fill 900 ft away under severe conditions. The average haul speed will be 14 mph and the average return speed will be 20 mph.
As the piston is compressed, the pressure also increases by 2000000 Pa. If there is 4 times as many atoms of nitrogen as helium, how many moles of helium are in the cylinder?
