Heat is supplied to an absorption refrigeration system from a geothermal well at 130°C at a rate of 5 × 105 kJ/h. The environment is at 25°C, and the refrigerated space is maintained at -30°C. Determine the maximum rate at which this system can remove heat from the refrigerated space.
A 10 storey building measures 20m x 40m in plan and has columnslocated on a grid 10m x 10m. The floor consists of a 250mm thick R/C slab with droppanels 3m x 3m x 200mm thick in the vicinity of each column. Live load allowanceis 3.0kPa.
The composite shaft is made of a steel sleeve, which is bonded to a brass core. The outer diameters of the two parts are d1 = 40 mm for the brass core and d2 = 50 mm for the steel sleeve.
If the coefficient of static friction between the 50-lb roller and the ground is 0.25, determine the max force P that can be applied to the handle, so that the roller rolls on the ground without slipping.
