Steam flows steadily through an adiabatic turbine.The inlet conditions of the steam are 6 mPa,400 degree celcius and 80 m/s and the exit conditions are 40 kPa, 92 percent quality and 50 m/s.The mass flow rate is 20 kg/s.Determine (a)the change kinetic energy,(b)the power output (c) the turbine inlet area
Determine the smallest horizontal force required to lift the 260- crate. The coefficient of static friction at all contacting surfaces is = 0.7. Neglect the mass of the wedge.
Water enters a hydraulic turbine through a 30-cm-dia pipe. The pressure drop in the turbine is measured by a mercury manometer to be 1.2 m. For a combined turbine-generator efficiency of 83%, determine the net electric output. Disregard the effect..
what are the properties of petrol that it makes particularly suitable for the use as afuel in a motor vehicle.
Important information about Compressive Stress, A circular cross sectional bar with a diameter of 3.25 inches is loaded with a uniform axial compressive load of 22,750 pounds. What is the compressive stress along a cross section of the bar?
A body having a mass of 46 kg rests on a horizontal planse for which the coefficiant of friction f = 0.4. A force P acts ofn the body at an angle of 20 degrees with the horizontal. Find its magnitude for impending motion.
Irrigation system
The tank air pressure above the water level is 300kPa(absolute) while the atmospheric pressure is 100kPA. Neglecting frictional effects, determine the initial discharge rate of water from the tank.(Density of water=1000kg/m^3)
a 2.5 lbf block b is moving with a velocity vo of magnitude vo 6fts as it hits the 1.5 lbf sphere a which is at rest
A 7/16 nut driver with a 1 1/2 inch diameter handle is used to install a 1/4 20 UNC bolt into a robotic arm. Determine the circumference where the effort is applied
The velocity at the inlet is controlled so that it changes according to the following expression. V=a-ct^2, where a = 20m/s, c- 0.8m/s. If the tank initially contains 3kg of liquid water, determine the final mass at the end if 4 seconds of flow.
A steel tape is used to measure a distance of 20 m at a 10 0C. Assuming that the tape will measure the true distance when the temperature is 20 0C. What would be the indicated distance at 10 0C? What would be the indicated distance at 400C?
