Chapter 36 - Transport in Vascular Plants | CourseNotes

Proton pumps play a central role in transport across plant membranes. The most important active transport protein in the plasma membrane of plant cells is the proton pump. It hydrolyzes ATP and uses the released energy to pump hydrogen ions (H+) out of the cell. Short-distance transport in plants, the movement of water and solutes from one

Passive transport and active transport across a cell

Movement Across a Membrane and Energy. There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done. Cartoon representing passive transport as rolling a boulder

Concrete Pumps | What is a concrete pump?

Schwing Stetter Mobile Truck Mounted Concrete Pumps. Our mobile truck mounted concrete pumps range from the two axle S20 with a 20 metre vertical reach to the 5 axle S61SX with a huge area in which in can place concrete and a towering vertical reach of 61 metres. With a large range of boom lengths and configurations, these popular, versatile machines are ideal for the majority of concrete

Hydraulic Ram Pumps - USDA

Today, ram pumps are installed and functioning worldwide. General Functioning Principles The basic principle behind ram pumps is to use a large amount of water falling a short distance to pump a small amount of water to a higher elevation. Typically, only 2% to 20% of the water flowing through a ram pump system will actually be delivered to the

Pumping of concrete - SlideShare

Feb 23, 2014 · These pumps are capable of pumping 130 m3 of concrete per hour with 8 inch pipes. 2. Squeeze pumps or peristaltic pumps are the ones that use vacuum pumping. These pumps can cover a distance of 90 m horizontally and 30 m vertically, and are capable of pumping 20 m3 of concrete per hour using 3 inch pipes. (a) Direct acting piston pump.

Stormwater Best Management Practices: Concrete Washout

concrete. Concrete washout. After concrete is poured at a construction site, the chutes of ready mixed concrete trucks and hoppers of concrete pump . trucks must be washed out to remove the remaining concrete before it hardens. Equipment such as wheelbarrows and hand tools also need to be washed down. At the end of each work

When to Use a Boom Pump vs. a Line Pump | Dynamic Concrete

Mar 22, 2019 · A boom pump is a concrete pump that you mount on a truck (hence it is sometimes called a "truck-mounted pump") and that uses an arm (the "boom") that you control remotely to deliver the cement where you need it. The main advantage of using such a pump is that it allows you to pump a lot of concrete in a very short amount of time, even

Concrete mixer - Wikipedia

A variant of standard concrete transportation is the concrete or cement mixing trailer. These small versions of transit-mix trucks are used to supply short loads of concrete. They have a concrete mixing drum with a capacity of between 1 and 1.75 cubic yards (0.76 and 1.34 m 3). Cart-aways are usually pulled behind a pick-up truck and batched
