What is the level after 30 mins of the water if the pump capcity is 750 gpm @ 9 bar and the water inlet supply to the tank is 50 mm with 5 bar pressure. (tank dimension is 10mx3.6mx3.4m(Lxwxh).

Is a room that is protected by FM200 should need to provide ventilation to exhaust the agent after discharged. If yes what should be the air change for this particular application.pls help.tnx!

I have a fire protection project, a 7 storey building. It supply sprinklers from the basement level up to roof deck. The roof deck are supplied by sprinklers but the no. of sprinkler on that level is only 5. Should I provide Zone Control Valve Assembly on that partcular level or should I tap the piping from the lower level afer the zone control valve.Thanks

How do I install the Flexible Joint coupling in expansion joints of the building.should be inside of the expansion or beside the expansion.Another thing is what are the components in considering the design of the coupling in building expansion joint.thanks

It is claimed that 80% of the people in the United States watched the first moon-landing on TV. If this claim is true, what is the approximate probability that In a sample of 100 polled at random, the number of people who saw the landing will be

a) less than 70?

b) greater than 86?

c) between 76 and 86, inclusive?

The letters from the word PROBLEM are arranged in all possible ways. If an arrangement is pick at a random, find the probability that two bowels are next to each other.

Suppose a box contains 100,000 beads, of which 30,000 are black and 70,000 are red. If 10 beads are picked at a random from this box, find the probability that there are:

a) 4 black beads

b) more than 4 black beads

c) at most 6 red beads

d) no black beads

Pls help me to calculate the no of sprinkler used to cool a Fuel Storage Tank with a diameter of 7.865m and a height of 10.98 meters.

We have a problem about an Oil spill in our pipeline, It happens when someone had cut a 10 inch pipe with a hack saw, thus oil (Banker Oil) starts to spill. our assignment is to stop the spill and retrieve all the remaining oil, since the the pipe had been shut down for many years..The question is what procedure(s) you can suggest to retrieve the remaining oil.Also the part that have been cut is not the lowest part of the pipeline so other part which is lower could not be taken readily.thank you

A vessel of 0.058 m^3 capacity is well insulated and divided equally by rigid conducting diaphragm.Initially both halves contain air pressure of 137.8 kpa and 413.4 kpa and a temperature of 27deg C and 177deg C respectively.What is the increase in entropy of the system in kJ/degC

a certain gas at 101.325 kpa and 16deg C whoose volume is 2.83m^3 are compressed into a storage vessel of .31 m^3. Before admission, the storage vessel contained the gas at a pressure and temperature of 137.8kpa and 24degrees Celcius. After the admission, the pressure has increased to 1171.8 kpa.What should be the final temperature of the gas in the vessel in kelvin?

in a box, there are 6 red balls and 7 blue balls.Two blue balls are drawn in the first and second draw. assuming the balls are not returned, what is the probability of getting at least 2 red balls in the next three draws?
