25 points The temperature of the earth's atmosphere varies according to the equation T=-0.0052 + 288.15 where T is in Kelvin and z is in meters. If the air temperature at ground level is is °C and pressure is 760 mm Hg. Assume air to be an ideal gas with an average molecular weight of 28.9 g/mol. At an elevation of 5,575 m what is the corresponding pressure in mm Hg? 0 380 0 280 480 O 880

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?
