Question

Liqufied gas ( LNG) is primarily compsed of methane in liquid form. Answer the questions below using the proerties given. Liquid methane density=0.40 Kg/cm^3 (0.40 Kg/liter), Heat capacity = 3.50J/gram.C, molar mass = 16g/mol

a) Liquid methane flows through a tube with an inside diameter of 0.80cm (are=0.50 cm^2) at a rate of 20grams/s. Whats the flow rate in liters/min?

b) whats the average velocity of the liquid methane in cm/s

c) if the liquid methane temperature is rasied from -80C to 30C, what rate of heating is needed for the 20grames/s flow?                 (   value                              unites)

d) whats the approximate volume of 80 grams of methane gas at 1.0 atm pressure and 0C?

          _____240liter                  ______112liters                             ______40.0liters                                ______0.240liters

Explanation / Answer

a) flow rate = 20 grams/s      ( using Volume = mass/density )

      flow rate = (20/400) litre /s = (20/400) litre /s x 60 = 3 litres/min

Flow rate litres /min =    3 litres/min

please post remaining questions separately...thanks
