Question 1 Correct Mark 4.00 out of 4.00 70678382: A03Q01 1.41 Vehicle hydraulic system Category: Assignment 03 The figure below shows a diagram of the hydraulic system for a vehicle lift. An air compressor maintains pressure above the oil in the reservoir. What must the air pressure be if the pressure at point A must be at least 204 psig. (provide your answer ( numerical value and units ) in psig with a precision of one decimal place) Answer: 201.9 psig The correct answer is: 201.9 psig
Question 2 Correct Mark 4.00 out of 4.00 70678384: A03Q02 1.42 Inlet pressure of washing machine pump Category: Assignment 03 The figure below shows a clothes washing machine. The pump draws fluid from the tub and delivers it to the disposal sink. Compute the pressure at the inlet to the pump when the water is static (no flow). The soapy water solution has a specific gravity of 1.16. (provide your answer ( numerical value and units ) in kPa with a precision of one decimal place) Answer: 4.3 kPa(ga (gage) The correct answer is: 4.3 kPa(gage)

Question 3 Correct Mark 4.00 out of 4.00 70678385: A03Q03 3.47 Height of liquid in tank Category: Assignment 03 For the tank shown in the figure below, determine the depth of the oil h if the reading of the bottom pressure gage is 38.6 psig, the top of the tank is sealed, and the top gage reads 27.7 psig. (provide your answer ( numerical value and units ) in ft with a precision of two decimal places) Answer: 26.48 ft sg oil = γ oil γ ref ( H 2 O , 4 C ) Δ P oil = γ oil × h oil Δ P oil = sg oil × γ ref ( H 2 O , 4 C ) × h oil P bottom gage = Δ P oil + P top gage P bottom gage = sg oil × γ ref ( H 2 O , 4 C ) × h oil + P top gage h oil = P bottom gage P top gage sg oil × γ ref ( H 2 O , 4 C ) h oil = (38.6 psig − 27.7 psig ) 1 lb in 2 1 psig 0.95 × 62.4 lb ft 3 1 ft 12 in 3 1 ft 12 in = 26.48 ft The correct answer is: 26.48 ft ( ) ( ) ( )

Calculate the air pressure above the gasoline if the gasoline's specific gravity is 0.714. (provide your answer ( numerical value and units ) in kPa with a precision of two decimal places) Answer: 43.65 kPa (gage) The correct answer is: 43.65 kPa(gage)
Question 5 Correct Mark 4.00 out of 4.00 70678390: A03Q05 3.62 Water pressure in pipe Category: Assignment 03 Water is in the pipe shown in the following figure. Calculate the pressure at point A in kPa if h is equal to 94 mm. (provide your answer ( numerical value and units ) in kPa with a precision of two decimal places) Answer: -13.47 kPa (gage) (gage) The correct answer is: -13.47 kPa(gage)
