Consider the conveyor system described in Problem 7.24, but under conditions for which the conveyor is not moving and the air is quiescent. Radiation effect sand interactions between boundary layers on adjoining surfaces may be neglected.
(a) For the prescribed plate dimensions and initial temperature, as well as the prescribed air temperature, what is the initial rate of heat transfer from one of the plates?
(b) How long does it take for a plate to cool from 300°C to 100°C? Comment on the assumption of negligible radiation.
a block of 10-in length and 1.8 times 1.6 in. cross section is to support a centric compressive load p. the material to
Steam at 3 MPa, 400C enters a turbine with a volume flow rate of 5 m^3/s. An extraction of 15% of the inlet mass flow rate exits at 600 KPa, 200C. The rest exits the turbine at 20KPa with a quality of 90% and a velocity of 20 m/s. Determine the volum..
Air at 60° F and 40 psia is flowing in a 4" diameter pipe at 0.2 slugs/sec. The pipe undergoes a conversion to a 2" by 3" rectangular duct in which T = 150°F and P = 7 psia. Calculate the average velocity in each section.
(a) The mechanical efficiency of the pump and (b) The temperature rise of water as it flows through the pump due to the mechanical inefficiency.
Three children are standing on a 5×5-m raft. The weights of the children at Points A, B, and C are 375 N, 260 N, and 400 N, respectively. If a fourth child of weight 425 N climbs onto the raft, determine where she should stand if the other children r..
a one shell two tube pass surface condenser is required to handle the exhaust from a steam turbine developing 14 300 kw
For a combined turbine-generator efficiency of 83%, determine the net electric output. Disregard the effect of the KE correction factors.
a small 0.6-lb collar d can slide on portion ab of a rod which is bent as shown. knowing that r 8 in and that the rod
The figure shows a typical V-truss A-B from a building crane. In this exercise the truss is considered as plane. The truss is supported by a fixed hinge at A and an inclined tension bar DC, connected to the head of the truss at C. It carries the v..
Air is compressed at steady state from 1 bar, 300 K to 5 bar 500 K using 150 kW of power. The compressor produces 50 kW of heat that is transferred to the surroundings. Assuming an ideal gas determine the mass flow rate of the fluid.
Determine the number of pounds of helium within it if its volume = 68,000 ft^3 and the temperature and pressure are 80 F and 14.2 psia.
