Question
Answer all the questions 1) Using dimensional equations, convert: 700 m* /(day. kg) to cem* /(min. g). 2) Convert 210 X 10 kJ/min to hp 3) Calculate the weight in lbr of a 30.0-lbm object. 4) Calculate the mass in kg of an object that weighs 25 Newton. 5) The density of a fluid is given by the empirical equation: p = 70.5 exp(8.27 x 10-7P) where p is density (Ib/ft) and Pis pressure (lb,/in.?). (a) What are the units of 70.5 and 8.27 x 10-7? (b) Calculate the density in g/cm for a pressure of 9.00 x 10 N/m?. 6) The vapor pressures of 1-chlorotetradecane at several temperatures are tabulated here. T(C) 98.5 131.8 148.2 166.2 199.8 215.5 p* (mm Hg) 1 5 10 20 100 60 Use two different method to estimate the value of P' at T = 190 °C (7) The specific gravity of gasoline is approximately 0.70. a- Determine the mass (kg) of 50.0 liters of gasoline. b- The mass flow rate of gasoline exiting a refinery tank is 1150 kg/min. Estimate the volumetric flowrate in liters/s.
