A Diesel cycle operates with a compression ratio of 13.5 and with a cutoff

occurring at 6% of the stroke. State 1 is defined by 14 psia and 140 F. For the hot air

standard with k=1.34 and for an initial volume of 1 cu.ft. compute a) Qr, BTU, b)

Wnet, BTU, c) thermal efficiency, %, d) mean effective pressure, psi. e) For a rate of

circulation of 1000 cubic feet per minute, compute the horsepower

An ideal Otto engine, operating on the hot-air standard with k=1.34, has a

compression ratio of 5. At the beginning of compression the volume is 6ft3

, the

pressure is 15 psia and temperature is 100F. during constant – volume heating , 500

Btu are added per cycle. Compute Wnet, Qr, thermal Efficiency, and mean

effective pressure.

A man used his prototype invention, the 3D Maneuver Gear, to navigate his hometown. He maintained his velocity of 96 m/s as he swung on top of a 15-storey building, his anchors placed 250 m away, at the height of 325 m. He swung 52.43° to propel himself up, then 35° to the West to reach his endpoint. How fast is he in all 3D components?

an aluminum tube with a 15 inch diameter with an average speed of 150 ft/min and specific volume of

two water tanks are connected to each other through a mercury manometer with inclined tubes as, shown in figure. if the pressure difference between the two tanks is 20 kPa . calculate a and angle teta

A drug is being delivered into a patient's arm at a rate of 10 mL min-¹. The drug is being delivered from a syringe through a 5 cm long needle with an internal diameter of 1mm. If patient's blood pressure is 110mmHg (+15.0 kPa gauge preasure, and ignoring the variation from systolic to diastolic), what must the pressure in thw syringe be? (ndrug= 8.90x10-4 Pa.s

A heating rated 100W is used to boil off 0.5kg of boiling water. the time to boil the water is ? (specific latent heat of vaporization= 2.30 × 10^6J/kg

Assume that a car decelerates at 2.0m/s2 and comes to a stop after traveling 25m.

a) Find the speed of the car at the start of the deceleration and

b) Find the time required to come to a stop.

A mass m of helium gas is in a container of constant volume V. It is initially at pressure P and absolute (Kelvin) temperature T. Additional Helium is added, bringing the total mass of helium gas to 3m. After this addition, the temperature is found to be 2T. What is the final gas pressure?
