Steel plate measuring 1m by 2m and of 5mm thickness intitailly at 500 degress C need to be cooled by air at 50 deg C and blowing at 20m/s. The air blows paraale to the shorter wdge. Estimate the convenction coeffiecient and thje initail cooling. The viscocity, specific heat and theraml conductivity of air at 275 deg C are 2.88E_)% Pa/s 1040J/kg/K and 0.0439 W/m/,respectively. Estimate the desnity of air using thre ideal gas law (R

Acompressor compresses a gas, a pump compresses a liquid. for a given pressure ratio, why does it take more work to compress a gas in a compressor than a liquid in a pump? a)- for a given pressure ratio the average specific volume for a gas is much higher than the average specific volume for a liquid. b)- there is no difference. the only difference is the amount of heat generated (not work) c)- for a given pressure ratio the average volurge for a gas is much higher than the average volume for a liquid. d)-there is no difference
