Find the internal energy of 1 kg of steam 10 bar, when the condition of steam is at a pressure of (a) wet with a dryness fraction of 0.85. (b) dry and saturated, and (c) superheated, the degree of superheat being 30°C. The specific heat of superheated steam at constant pressure is 2.01 kg-K

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

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.

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.
