Drive Submersible
Nordic "three Male" Sub
Independent marine tank with liquid cargo Pump Market mainly by the Nordic Norwegian Framo, the Netherlands and Denmark HamworthySvanehoj Marflex share three large companies, their marketing methods and product characteristics of each type.
Norway FrankMohn Corporation (Framo) In the next few years into the new market of refined oil and chemical tankers, there will be more than 1,000 vessels equipped by the Norwegian FrankMohn Corporation (Framo) provided by the hydraulic drive submersible pumps, the ship's sea boat from 2000dwt to 120,000 dwt in the LRI-class product tanker.
The company in 1969 for the first time a Belgian shipyard built eight chemical tankers supply the hydraulic driven cargo pump. Since then, Framo Although the company expanded production and global network, but always the supply of hydraulic system. Now the supply pump for the single pump displacement 50-2000 cubic meters / hour, the total displacement pump up to 15,000 cubic meters / hour.
This pump system installed in the barges, chemical tankers, product tankers, large oil and OBO vessels and FPSO / FSO vessels. Framo said, now operating more than 2,300 tankers vessels using the company's system, a total of 40,000 sets of the tank with a hydraulic drive pump.
Netherlands Marflex company Netherlands Marflex in this area have great success. However, it is a special supply of electricity-driven pumps manufacturer of vertical motor mounted on the deck. The company is taking the opposite route of technology, insufficient emphasis on the effectiveness of electric drive.
Marflex every success. 2007, volume of business increased 40% in 2006. Sales volume in 2008 than 2007, more than 60%. Part of the proceeds used for investment to expand its production and logistics capabilities. These include a new purpose-built 5,000 square meters of workshop, which equipped with the most advanced lathes and welding machines.
Denmark HamworthySvanehoj company In the same field of professional firms, Danish HamworthySvanehoj also promote the use of electric pump, it does not need pumping stations, can be used for crude oil tankers, product tankers, chemical tankers and gas carriers. The factory in Denmark Svanehoj built a 1200 square-meter warehouse in order to meet the weekly production of 2 sets of marine pumps. Hamworthy marine pump sales manager said: "Today's workload, including the past 4 years in Turkey, such as the construction of more than 100 vessels oil and chemical tankers used Deep well pump And is expected to include parts of the world production this year 75 boats are equipped with LPG deep well. "Turkish-built vessels ranging from 2200dwt to 25000dwt, the pump delivered to the country has been extended to 2010.
HamworthySvanehoj in the development of deep-well pump area nearly 40 years of experience. Initially, the company's pumps are mainly exported to Europe, the Far East supplier to the major breakthrough was in 1984 by Hyundai Heavy Industries for the TurnhullScott company built 10400dwt "SanNicholas" number of tankers providing marine pump. Since then, the company has gradually extended to the deep well for Malaysia, China, Singapore and Japan, new oil and chemical carrier, South Korea is also a significant increase in orders.

Pressure gauge Physics problems--help?
1. Scientists have found evidence that Mars may once have had an ocean 0.500 km deep. The acceleration due to gravity on Mars is 3.71m/s^2.
a.) what would be the gauge pressure at the depth of 0.184 km of such an ocean, assuming it was freshwater? (answer in Pa please)
b.)To what depth would you need to go in the earths ocean to experience the same gauge pressure?(answer in m please)
2.An electrical short cuts off all power to a submersible driving vehicle when it is 33.3m below the surface of the ocean. The crew must push out of a hatch of area 0.75m^2 and weight 320N on the bottom to escape. If the pressure inside is 1atm, what downward force must the crew exert on the hatch to open it? (answer in N please)
1)
a)
Pressure = density * g * h = 1000 * 3.71 * 0.184 = 682.64 Pa
b)
Pressure = density * g * h
For same pressure:
h = Pressure/(density * g)
= 682.64/(9.81*1000) = 0.0696m
2)
Pressure at that depth = density * g * h = 1000 * 9.81 * 33.3 = 326673 Pa
Force on the hatch due to pressure = Pressure * area = 0.75 * 326673 = 245004.75 N
I don't get whether the question is says the hatch is at top and the crew must push it up or it is at the bottom and the crew must push down. If the hatch is at top and crew must push up, the weight will work against them. Hence total force exerted will be (245004.75 + 320 = 245324.75 N). If the hatch is at the bottom, and the crew must push down to escape, the weight will work for them and help them hence the force exerted will be (245004.75 - 320 = 244684.75N).
