Assume 4.5 kg/sec of steam at 305°C, 1.5 Mpa expands isentropically in a turbine and exhaust at 138 kpaa, AP=0, AK-0. Sketch the process on the TS plane and find a) Exhaust temperature t₂, b) Work in Kw and KBTU/hr.
A rigid vessel contains 6 kg of wet steam at 0.4 MPa with a quality of 75% until the steam
has a temperature of 300C. Determine the initial internal energy and the final pressure.
Liquid A decomposes by first-order kinetics, and in a batch reactor 50% of A is converted in a 5-minute run. How much longer would it take to reach 75% conversion?
n a slab milling operation the diameter of cutter is 50 mm and number of teeth of cutter is 12. If the
cutter spindle speed is 300 rpm, depth of cut is 2 mm, length of job is 500 mm and table longitudinal
feed is 200 m/min what will be the feed per tooth during the milling operation? If the cutter over travel
is 2 mm what is the machining time for the single pass milling operation?
A mild steel square tank with a wall thickness of 8mm contains water at 80˚C. The thermal conductivity of amild steel is 50W/m.K and the heat transfer coefficients for the inside and outside of the tank are 2800W/m2.K, and 11W/k2.K respectively. Sketch and label the temperature profile and calculate the rate of heat loss per m2 of tank surface area when the atmospheric temperature is 25˚C.
100 liters of certain liquid has a mass of 85 kg. Determine the specific weight and gravity of the liquid
1 ton Zinc concentrate which is include 60% ZnS, 33%Fe2O3, 7%SiO2. 20% Ore Charging Mass Weight Coal used for Calcination Process. Coal is include 72 % C, 6%H2, 10%Sulphur and 12% ash. All volatile gasses are throw away gasses out chimney, and ash from coal do not join Zinc concentrate. Ore body concentrate 3% ZnS didn’t effect from Calcination. Oxidation Products are ZnO, Fe2O3 and SiO2. Used air was applicated 50% added air from required. Please calculate air amount by volume, and chimney gasses by volume and find percentage chimney(stack) gasses.
