Steam at 2.0MPa and 350 deg C, flowing at a rate of 2kg/s is throttled to a pressure of 800kPa and is then mixed with the steam of 800kPa and 0.95 dry, which flows at a rate of 4kg/s. Find the diameter of a pipe to convey the superheated steam flowing into the mixing process if the speed of the steam is 20m/s and also ascertain the condition of the resulting mixture.
The bent rod ABDE is supported by ball-and- socket joint at A and E and by the cable DF. If a 600-N load is applied at C as shown , determine the tension in the cable.
Calculation of percentage heat reduction, Water at 90 C flows through a 50mm bore steel pipe of wall thickness 8 mm. Ambient temperature is 18 C. Calculate the heat loss per metre length of pipe
Finding exit velocity from air nozzle, Air enters a nozzle operating at steady state at 800 ºR with a negligible velocity and exits the nozzle at 570 ºR.
The nominal breaking strength of the rope is 10,000 lbs. Calculate how much payload this assembly can allowably pick up. Show your work.
Determine the acceleration of the cabinet when sA = 40 ft. Note that when sB = 0, sA = 0 (points A and B are coincident).
The piston is then move in,and heat is rejected bt the air reversibly at constant pressure until the volume is the same as it was initially.Calculate the net heat flow and the overall change of entropy.sketch the process of p-V and T-s diagram.
Knowing that the coefficient of restitution is 0.8 between B and C, and 0.5 between A and B, Determine the velocity of each car after all collisions have taken place.
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.
