B: drive the theoretical head - discharge relation in pumps then show the effect of the exit blade angle on this relation.

What is the static air powering watts of a fan designed to deliver 800 m^3/hr of air with a static pressure of 5 cm water column on full delivery.

3. A simple steam power plant illustrated below uses 20 kg/s of steam. Find: a) the boiler heat transfer rate; b) the turbine power output; c) the condenser duty; d) the pump power required. What is the ratio of net power out to heat in (the thermal efficiency)? The turbine and the pump are adiabatic 2 Boiler Pump 2 3 |3|4 Stream T(°C) P(MPa) 40 40 Turbine 600 x = 1 Condenser 0.01 10 10 0.01 A

a. Water flowing at 2.6 KL/s is taken from a river and delivered to a turbine 100m lower than the source. If the turbine/generator has an efficiency of 45%, calculate the electrical power that would be delivered over one year. b. Explain, with the aid of suitable graphs, the charge and discharge cycle of a deep cycle lead acid battery. c. In a thermal power plant, 1500 MWh of energy is to be produced in a day, half from oil and half from natural gas, Calculate, for a one year period: the number of barrels of oil required if the fuel oil plant is 40% efficient. the total amount of natural gas required if the efficiency of the gas plant is 48% If a coal plant of 45% was used to supply the full load for a week, how much coal would be required? Use the following conversions in your calculations. Fuel & Energy Conversion & Equivalence Chart (reduced) http://www.cogeneration.net/FuelAndEnergyConversionandEquivalence.htm 1. Fuel Oil: 1 Gal of #4 Fuel Oil - 145,000 Bou's 1 Barrel of Oil -42…

For an impulse steam turbine of De Lavel type, the nozzle having an angle of 16°, delivers 1 kg of steam per sec at a speed of 720 m/s to a set of blades moving at 180 m/s. The blade angle at outlet is 25° and blade velocity co-efficient is 0.72. Determine the following: 1.  Power of the wheel in kilowatt. 2. Blade efficiency in Percentile (%) 3. The energy lost in the blades in kJ/kg.
