Consider the following cyclic process carried out in two steps on a gas:
Step 1: 45 J of heat is added to the gas, and 10. J of expansion work is performed.
Step 2: 60. J of heat is removed from the gas as the gas is compressed back to the initial state.
Calculate the work for the gas compression in Step 2.
One type of commercial smoke detector contains a minute amount of radioactive americium-241 (241Am), which decays by -particle production. The particles ionize molecules in the air, allowing it to conduct an electric current. When smoke particle..
What is the purpose of a suture? What are some of the important properties that must be considered when selecting a biomaterial for use as a suture? List four biomaterials that are commonly used for sutures.
What is the identity of the solid? Give the balanced equation of this species decaying by -particle production. Why is the solid a more potent a-particle producer?
A storage tank is purged continuously with a stream of nitrogen. The purge stream leaving the tank is saturated with the product stored in the tank.
For the purpose of comparison, obtain the corresponding SOP circuit, and comment on the number of gates needed.
Assume a 10 °F temperature between streams in the heat exchangers and a compressor efficiency of 80%.
adsorption and membrane processeszeolites are used to adsorb a wide range of solutes from vapour and gas streams. what
Plot the system curve on the pump characteristic given in Figure 20.17 and determine the operating point and pump efficiency. Properties of the fluid: density 900 kg/m3, viscosity 1.36 mN m-2 s.
Calculate the equilibrium conversion and the CSTR and PFR volumes necessary to achieve 98% of the equilibrium conversion and calculate the time to reach 90% conversion if the reactor is a batch reactor filled to the brim.
In Number 1 it was assumed that the input and output flow rates could be independently varied. Consider a situation in which the outlet flow rate is a function of the height of liquid in the tank. Write the modelling equation for tank height assum..
determine the diode current and voltage and the power delivered by the voltage source. The diode characteristic is given in Figure P7.2.14 (b).
Where 'k1' and 'k2' are rate constants,tR,maxis the time at which the maximum concentration of 'R' is obtain and CR,maxis themaximum concentration of 'R'
