Demonstrate the principle of the Solovay and Strassen primality test on the number m = 33 The number m has been made small in this problem to keep the calculations simple. So, do not make use of numbers that "incidentally" have a factor in common with m.
A human being (75 kg ) consumes about 6000 Kj of food per day. Assume that the food is all glucose and that overall reaction is- C6H12O6 +6O2 ------à 6CO2 +6H20 , Δ H= -2816 KJ
6. Famous New Zealand scientist Ernest Rutherford was awarded a Nobel Prize in which field? 7. What is the chemical symbol for gold? 8. K is the chemical symbol for which element?
What is the very largest torque T that can be applied with elastic behavior everywhere? (Hint: cut combined shaft at C and consider separate shaft). What are the supporting torques?
Calculate the relative change in the rate coefficient for the reaction at the Earth's surface (T = 295 K) and at the top of the troposphere (T = 220 K). The reaction has an activation energy of 19.5 kJ/mol.
A mixture of 25% ammonia gas and 75 % air ( dry basis) is passed upward through a vertical scrubbing tower , to the top of which water is pumped. Scrubbed gas containing 0.5 % ammonia leaves the top of the tower, and an aqueou..
Calculate the temperature change when 10 mol of benzene is mixed with 40 mol of heptane adiabatically, 1 bar., if the initial temperature of the pure components is 20 °C. The heat capacity of the pure liquids are CP 1 = 134 J/mol, CP 2 = 222 J..
The efficiency at rated load, 0.8 power factor lagging, and at half-load, unity power factor.
When burnt , the flue gas issuing out of the furnace at 545 oc analyses on dry basis as CO2 =14.5 % , O2 = 4.7%, N2 = 80.8 % , Other relevant data are- Gross C.V. of coal =28000 kj /kg , ambient temperature = 15oc
determine the ratio of starting torque to full-load torque.
Steam at 2700 kPa and with a quality of 0.90 undergoes a reversible, adiabatic expansion in a nonflow process to 400 Ha. It is then heated at constant volume until it is saturated vapor. Determine Q and W for the process.
A stream of ethane gas at 493.15 K (220°C) and 30 bar expands isentropically in a turbine to 2.6 bar.
Select any process/chemical engineering topic of your interest and in about 1000 words explain how modeling is involved in its study and development. regards Mohammed
