Wells PW-1 and PW2 are pumped continuously over a period of 50 days. Well PW-1 is pumped at a constant rate of 4 gpm. PW-2 is pumped at 2 gpm for 20 days and 4 gpm for 30 days.
Calculate the water level at observation well O, situated at an equal distance of 100 ft from both the pumps, after 50 days of pumping.
T = 1,000 ft^2/day; S = 1 x 10^(-4).

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
