Distinguish between a Hazard and Operability Study (HAZOP) andHazard Analysis (HAZAN).(b) Explain briefly the quantities shown in the equations used for hazardanalysis H = D . fdt = D ×1/2F . T (if F . T << 1).(c) State the units of H and D and hence determine the units of fdt if any.(d) FIGURE 1 shows an external intermediate vessel which receives acontinuous mixture of hydrocarbon liquid and small variableamounts of water. The water must be separated by settlement intothe sump to prevent contamination of a later hydrocarbon processingstage. The sump should be drained every 4 hours by an operator.The operation is facilitated by a sight glass and high level alarm.Under normal conditions the sump would fill in approximately10 hours.Carry out a hazard and operability study (HAZOP) on the sump anddrain line for deviation of 'No Flow' and 'More Flow' of water, listingpossible causes, consequences and recommendations to avoid futuredeviations.
The tower is held in place by three cables. If the force of each cable acting on the tower is shown, determine the magnitude and coordinate direction angles of the resultant force. Take x = 20 m, y = 15 m
the combustion products in an internal combustion engine undergo an expansion process from an initial volume of 0.007
Determine the mass flow rate per unit frontal area. Assuming the flow is isentropic, calculate the exit Mach number and the static pressure ratio across the cascade.
steam is leaving a pressure cooker whose operating pressure is 30 psia. the amount of liquid inside the pressure cooker
given a variable speed centrifugal pump initially pumping 32000 pounds mass per hour lbmhr at a discharge pressure of
Consider a mass going through a polytropic process where pressure is directly proportional to volume (n=-1) the process starts with P=0,V=0 and ends with P=600kPa,V=0.01m^3. Find the boundary work done by the mass.
water is the working fluid in a cogeneration cycle that generates electricityand provides heat for campus buildings.
Describe 3 methods used to measure the viscosity of a fluid. Can the methods used to measure the density and viscosity of a fluid be used to measure density of solids? Explain
Design a gear train which satisfies the above criteria. Use a sketch to illustrate your design, label the gears A, B, C, etc. from the driver to the driven gear, and state the number of teeth on each gear.
a) It is observed that the velocity 'V' of a liquid leaving a nozzle depends upon the pressure drop 'P' and its density ρ. Show that the relationship between them is of theform V =C * sq(P/ρ)
