A pressure control valve is actually called a hydraulic choke. Its work is to control pressure during drilling operations and during a kick (blowout). The pressure is controlled with relative modification of the control elements, gate, and seat, by moving the gate. to control this, the choke is fitted with a hydraulic actuator with a double acting piston.


While drilling, one must know the control element position, the gate, towards the seat. All controlling information is shown at the drilling choke control panel, where the operator stands. The panel shows the gate displacement expressed in percents from the maximum value of the gate stroke.

Gate and seat are compound with tungsten carbide, reversible for double life period.

Suppose you are buying a car. How would the trade-offs disscussed above affect your decision?
8_murik_8 [283]

Answer:

When purchasing a vehicle it is important to weigh out your decisions prior to your purchase. Safety is very important but it comes with a price. For example if you want airbags and anti-lock brakes you will need to buy a newer vehicle and that will cost you more money. If you want to drive a larger SUV that will protect you more because of its size you will be paying more for gas. It all comes down to a person's views on safety and personal freedoms...and of course cost of the vehicle. For me it will always boil down to cost and efficiency of the vehicle.

Explanation:

I did the homework in class and got it correct.

lapo4ka [179]

Answer:

The duties under the contract are agreement, consideration, legality, and capacity.

Explanation:An assignment of contract occurs when one party to an existing contract (the "assignor") hands off the contract's obligations and benefits to another party (the "assignee"). Ideally, the assignor wants the assignee to step into his shoes and assume all of his contractual obligations and rights. In order to do that, the other party to the contract must be properly notified.
