Question

На какую предельную высоту можно поднять нефть, поршневым насосом. плотность нефти р=750 кг на м в 3 степени, атмосферное давление 100кПа g=10H/ кг

Answer 1

P=p*g*h
h=P/p*g=100*10^3/750*10=13,3 м

Answer 2

Maximum Pumping Height for Oil with a Piston Pump

To calculate the maximum height to which oil can be lifted using a piston pump, we can use the following formula:

Maximum height (h) = (Pump work output) / (density of oil * acceleration due to gravity)

Given: - Density of oil (ρ) = 750 kg/m^3 - Atmospheric pressure = 100 kPa - Acceleration due to gravity (g) = 10 m/s^2

Using the given information, we can calculate the maximum height to which oil can be lifted with a piston pump.

Calculation

The pump work output can be calculated using the formula: Pump work output = Pressure difference * Volume of oil pumped

The pressure difference can be calculated using the formula: Pressure difference = Atmospheric pressure - Pressure at the pump outlet

However, the specific pressure at the pump outlet is not provided in the given information. Therefore, it's not possible to calculate the exact maximum height without this information.

If you have the specific pressure at the pump outlet, please provide it, and I can help you calculate the maximum height to which the oil can be lifted with a piston pump.
