HI THERE ARE 29.922  US QUARTS IN  ONE CU FT    OR    24.9154 IMP QUARTS IN ONE CU FT

DIVIDE YOUR REQUIRED QUARTS    380 / 29.922 = 12.700 CU FT US OR

                                                                     380 / 24.9154 = 15.252 CU FT  IMP

HI YOU HAVE SOME THING WRONG WITH YOUR QUESTION AS  YOU CAN NOT HAVE LIQUIDS AS  CM  I ASSUME YOU MEAN CENTI -LITRES

SO YOU HAVE A TANK 4M X 3M WITH 7200000CENTI-LITRES OF WATER

THERE FORE    LENGTH X WIDTH X HEIGHT  = VOLUME

HI YOU HAVE SOME THING WRONG WITH YOUR QUESTION AS  YOU CAN NOT HAVE LIQUIDS AS  CM  I ASSUME YOU MEAN CENTI -LITRES

HI   TO FIND THE SQ ROOT OF A NUMBER  IS THE OPPOSITE OF THE SQ OF A NUMBER  IE:

100  THE SQ ROOT IS 10        THE SQ ROOT OF A NUMBER  IS A NUMBER WHICH MULTIPLYED BY ITSELF GIVES YOU THE ORIGINAL NUMBER

EXAMPLES        9  SQ ROOT   = 3  AS   3 X 3 = 9      49 SQ ROOT =  7    AS  7 X 7 =49

THESE ARE EASY EXAMPLES  FOR MORE COMPLICATED  NO'S  YOU WILL NEED A CALCULATOR OR MATHS TABLES BOOK

HI  IT IS IMPOSSIBLE TO CALCULATE AN ACCURATE MPH WITH OUT FRICTION COEFICIANTS ETC  BUT AN APPROX FIGURE CAN BE CALCULATED AS FOLLOWS

WORK OUT THE VOLUME PER MIN IN YOUR PIPE MULTIPLY BY 60 TO MAKE IT PER HR THEN DIVIDE BY 5280 TO MAKE IT MPH

IE:     1.25 X Pi   =    1.25 X 3.14159 =3.9269 sq in  =   0.32724 sq ft

DIVIDE THIS INTO       125/0.32724 = 381.98 FT PER MIN X 60  =22918.958 FR PER HR

DIVIDE BY 5280 WHICH IS FT IN MILE      22918.958/ 5290  = 4.3407 mile per hr

ASSUME YOUR SMALL NOZZLE IS    1/4inch dia

1/4 X 3.14159 = 0.786 sq in  =   0.0655 sq ft      125/.0655 =  1908 ft per min x 60 =114480ft per hr    divide by  5280         114480/5280 =   21  mile per hr   approx

AS I HAVE ALREADY STATED THIS IS A VERY CRUDE APPROXIMATION AS THERE ARE A LOT OF VARIABLES WHICH HAVE TO BE TAKEN INTO ACCOUNT

HI

The compression ratio is a single number that can be used to predict the performance of any internal-combustion engine. Basically its the volume of the cylinder at full intake to the volume at full compression.
The ratio is calculated by the following formula:

, where
b = cylinder bore (diameter)
s = piston stroke length
Vc = volume of the combustion chamber (including head gasket). This is the minimum volume of the space into which the fuel and air is compressed prior to ignition. Because of the complex shape of this space, it usually is measured directly rather than calculated.
Due to pinging (detonation), the CR in a gasoline/petrol or LPG or CNG-powered engine will usually not be much higher than 10:1.
In engines with a ping sensor and an electronic control unit, the CR can be as high as 12.5:1 (2005 Audi A6 3.2)
In a turbo charged or super charged engine the CR will be around 8.5:1
In a diesel engine the CR will be 20:1 and higher.

I HOPE THIS EXPLAINS  CR OK FOR YOU IF YOU WANT FURTHER INFO LOG ONTO GOOGLE  SEARCH ENGINE AND ASK YOUR QUESTION THERE WILL BE THOUSANDS OF SITES EXPLAINING IT IN MORE DETAIL

HI IF YOU MEAN  6.28CU MTRS  THEN THERE ARE A 1000 LITRS PER CU MTR

THEREFORE  6.28 X 1000 = 6280 LTR

IF YOU MEAN    6.28 X 6.28 X 6.28 = 247.673 CU MTRS   =   247.673 X 1000 = 247673.15 LTRS
