A 20-mm-diameter sphere is suspended in a dry airstream with a temperature of 22°C. The power supplied to an embedded electrical heater within the sphere is 2.51 W when the surface temperature is 32°C. How much power is required to maintain the sphere at 32°C if its outer surface has a thin porous covering saturated with water? Evaluate the properties of air and the diffusion coefficient of the air-water vapor mixture at 300 K.
Apparatus that liquefies helium is in a laboratory at 296 K. The helium in the apparatus is at 4.0 K. If 150 mJ of heat is transferred from the helium, find the minimum amount of heat delivered to the laboratory.
the blade assembly of an oscillating fan rotates with a constant angular velocity w1 -360rpm i with respect to the
A helical compression spring made from hard drawn wire needs to be designed to fit inside a 50mm cylindrical cavity and there must be enough space inside the coils for a 20mm cylindrical guide rod.
The object of this project is to develop the preliminary design of a bench-top laboratory set-up with which to evaluate the performance of a vapor-compression refrigeration system subject to broadly variable thermal inputs and changing ambient con..
the water in a 25 m deep reservoir is kept inside by a 150 m wide wall whose cross section is an equilateral triangle.
determine the maximum pressure across a 10 hp pump that has an inlet diameter of 1.0 inches and velocity of 10 fps. the
water is flowing through a large circular conduit with a velocity profile given by the equation v91-r216 ft per second.
It is desired to limit the centerline deflection of the spandrel beam (Fig. 4.41) to (1/288)L, where L is the length. Expressed in terms of the usual beam parameters (E,I,L,P), how small must the load P be so as not to violate the constraint? .
A laminated plastic beam with a square cross section is built up by gluing together three strips, each 10 mm × 30 mm in cross section. It must carry a load P at its midpoint.
The rigid bar AB has a mass of 24 kg, and the damping coefficient of the dashpot is c = 3 kN · s/m. The bar is driven by a vertical force (not shown) P(t) = 0.5 sin 25t kN acting at B. Determine the displacement amplitude of end B of the steady-st..
